I had trouble getting a spark plug for the same machine . I went to Lowe's Home Depot advance auto and auto zone no one had that type plug in champion or ngk I had to order one if it may help you the same plug in champion brand is ry4c. The ngk or torch number is cmr7a If you find a plug that looks the same size but the first letters are different don't use it I found out those first letters on ngk or torch plugs means the threads are different and different pitch so make sure tide first letters are what you want
Thanx I pinned your comment
Wally world has mostly all mower and weedeater sparkplugs for about $2-$3 each.
@@jwayne777 Good to know!! Tanx
One question what was that 2 cycle cleaner you kept squirting on all parts? I I couldnt quite make out what you were saying. It was in thst 4 oz bottle.
what are the fluids you use for cleaning while fixing? 2-stroke and trany fluid? What exactly and thanks.
Sure,,, check out my short!

I haven't changed my oil in 10 years. The bubble on the back has a crack in it that i need to replace.
Ohhhh NOT GOOD!! I put SHAME in your direction lol,,,,,,,These machines that use crankcase oil use very little and tend to burn it up quick.. My bet is if we change it every season we can avoid the horrors! Thanks fer posting
Note: If you want to save to time, you can purchase entire new carb, fuel lines, and primer bulb on line for about 15 bucks. Experienced great results bringing my Ryobi 4 cycle back from the dead.
Yup,,and now I'm set up with HIPA parts and they are very good.
Keep in mind there are differences from original. This can throw many people a curve ball. Due to patent issues some change is required unless one is buying OEM
Thanks for watching!
Dude, just measure the valve lash on the camshaft instead of the valve shaft.
Nice, didn't look to see if I could.
Never did one of these before and haven't seen one here in the shop since, probably wont again as these machines are coming to the end of their useful life.
Manual specifically says you are checking the rocker arm to cam clearance.
operator manual?
Great video! what oil do you recommend using in the unit?
Thanx Chevy!
10w30 or any good oil but most important,,,,change it often and keep it full!
Thank you!@@TheNovaJohn
This guy is OCD that makes him great.
lol,,,Thanks!
I have one of these. Unfortunately my cam was cooked.. and I can't get a spare for it.. good one mate
That's a shame, and very common. at the end of the vid I recommend strongly to change the oil every season. it doesn't have much oil
This ran really nice and sounds awesome
Excellent video, sir!
Thank you for the great sound of nature.
Big Blocks forever!
Have one changed carb, fuel tank, and ignition coil. String spins but still won’t start even with new spark plug. Even sprayed it with starting fluid. Hate to trash it because I have all the attachments
Do a compression test, this way you know the engine is good, I always start with that otherwise its good money over bad!
hey arch, i use to love working on small engines. i see a lot of these having belt problems. you would think ryobi would be smart enough to make the gear on the cam shaft to have both sides with a lip. that would keep the belt from jumping time, but then again how would they make any money. as we all know, its cheaper to buy a new one than spend the same amount to fix. unless you know small engines and if you do not, we always have you. good video.
Lol,,,thanks Joseph,,,,,This was one of my 1st videos...
Its a good machine for the price but your correct, it has issues. Ryobi has gotten much better
Thanks for watching!
Double lip, great idea but maybe problem getting belt over that lip. The problem is the cam bearing going bad. If the cam bearing is good the belt rides perfect. And yes, a new one is cheaper if you have to pay someone to fix it. I know how to fix these but to take the total engine apart including the crank to replace a belt is a joke, not worth it!!
Q
Thank you!
So I don't understand what the problem was? Was it the thing you did with valves, or cleaning the spark plug, or adjusting that screw thing on carb? Mine currently likes to stall out and doesn't stay running. Then when warm it will stall and refuse to start. Trying to troubleshoot that
This is an older video and that machine is long since sold off.
What I show is going over an engine, everything needs to be correct if we want it to run properly.
where the hell did you get that carb adjusting screwdriver?
Try HIPA
www.hipastore.com/
I just bought an aftermarket carb and adjusting screw isn't pacman (need to look at original) but AFM looks has one pin hole just inside the outer circumference. Trying to imagine how the tool is made
Usually tools like this are punched under pressure when red hot.
@@gadasavideos8564 Its called a 'Single-D'. There's a large and a small, this WYL carb uses the small.
This has probably been asked before but what is the ratio of 2 stroke to tranny fluid? Also any particular type of tranny fluid?
Thanks
any tranny fluid!
Check this out!

Just subscribed. Working on same model. Talk about condition oil, when I checked oil I thought I was going to puke. What little was in there looked like moly lube. Changed it 3 times. Good information for a novice small engine mechanic. Thanks. Good day 🇺🇸
Thanks!!,,,good luck with yours!!! I think these are very good machines!!
will valve adjustment keep that from running full R{PM did you say .004-.005?
Yes it could but you need to check the carb to make sure the throttle is opening fully and its clean/operational
The 4-stroke piston gets its lubrication from the bottom oil splashing off the crank shaft similar to all 4 strokes. If it sucks in oil into the carb it will smoke like heck. My s430 was run low or out of oil before I got it and ruined the piston rings so that creates blow by into the crank case which blows allot of oil out of the top valve train and into the breather line going to the air filter housing and why mine has so much oil in and around the air filter and entering into the carb and getting burned and creating huge smoke. My engine is trash, and of course the cam bearing is trash also with oil blowing out of that bearing and all over the belt and front of engine. With no blow by the crank case breather lines would work fine. And thanks for the great video!!
Thanks Grant,, this was one of my 1st vids!
Makes sense, I mentioned that they have sooo little oil and it needs to be changed every season!
Some people say that ya cant flip it upside down? I don't know, I sold this one running well and I use my stihl,,,
Link below lol
ruclips.net/video/6snwd0eyrW4/видео.html
mine starts and idles. but to take the choke off u have to rev it and adjust the lever fast or it dies. im assuming the carb is clogged or something
Yep,,I would start with a carb rebuild/cleanings or replace it. Clean out the gas tank and pickup filter.
Check out the HIPA website for parts

Nice video. I'm still trying to get my carb passages cleaned out. The ultrasonic cleaner I have just doesn't work well. By the way is that a Walbro WYL carb?
I don't remember, I may have mentioned it.
If your carb is really dirty consider buying a new one!
I'm not a fan of those cleaners for automotive and small engines. It's important to get the mixture of cleaning solution right.
Thanx fer watchin!
I have three of these that each runs a little better (or worse) than the other. Since my wrist can't handle the vibration anymore, I plan on fixing them up, selling and buying electric. Thanks for the detailed video.
Hey great idea!! I like the small electric units for the casual home work!!
Good luck with ya projects and sales!!
Thanks fer watching!
Ciao ne ho anch'io uno uguale ma che misure hai fatto per le valvole di scarico e benzina???
Where is the high speed adjustment on these Ryobi S430s? Idle speed is easy and low is right down the carb shaft. I've read that the high is fixed, but I keep reading commentswhere people claim they adjusted the high. Thank you.
Take a look at the sequence again; I adjusted the Curb Idle Screw (throttle angle) this sets the idle speed by opening up the throttle blade.
It may need re adjustment later then adjust the fuel / air adjustment screw (packman) in the video.
This controls the fuel and air delivery and its really handling both the idle circuit and high speed.
I like to leave it a bit rich.
Most 4 stroke trimmers are like this. It runs well and doesn't miss a second/separate screw,,,
Thanks for watching!
You adjust the valves on sbc with it running if you want it done right. No feeler gauge needed. But you don’t need one for cold initial lash setting either…
It depends on the lifter design; this little guy has a solid lifter.
I ran ROADS lifters for a time on my 283, it loved them but they must be lashed to work properly.
Generally with hydraulic lifters ya put a lash on them when installing them for the 1st time. But the recommended way is to look down at the lifter keeper lock and just depress the plunger enough so that its off the lock (Preload).
This is a must for most Hi-Po lifters.
I didn't get this right once and when the lifter floated it popped that keeper ring and it went down into the engine..
I have the same unit but mine doesn't have an adjustment screw on the carb.
You can get a carb with it! May help
can you describe the two stroke and tranni fluid for me please
sure,,, take some 2 stroke fuel then mix in about 1/3 of the amount of tranny fluid
The gas itself is a very good vehicle, it will wick in the 2 stroke oil and the tranny fluid.
Tranny fluid is very good as a lubricant and its has a lot of detergent in it.
Why gas? Why not, all lubricant vehicles are flammable but gas evaporates quickly leaving the oils behind!
Final comment, trashed all Ryobi 4 strokes, can't take the problems anymore. Not worth it. G
I feel ya pain!!! They don't make anything to last at all these days
@@TheNovaJohn I use the Ryobi full crank two stokes/string trimmers, cheap and do a great job and last years, EXCEPT FOR THE COILS but coils are cheap and easy to install. Only other problem is the crank bearing on flywheel side wears out after severe usage, but it still runs if you move the coil away from the flywheel a bit so flywheel doesn't hit the coil because of the bearing play. I have my workers using these units at full throttle 8 hours a day for years. But we mix 20 to 1 gas to oil which I think is mandatory for any 2 strokes.
Amazing vid again and thanks for the shout out ...and yes the word is aluminium well spoken your English will soon be as good as Dr Susannha Lipscomb ;) :) :)
LOL,,, I hope she appreciates my effort!!
What is the training fluid you're using? 2stroke training fluid?
Tranny Fluid, transmission fluid, about 1/2 gas
Just driving home will be watching when I get home mate
LOL Drive safe!!
No it's chinesium LOL.
informative video, thank you. Are these walbro wyl carbs adjustable (or have hidden adjustment)? I have an older ryobi trimmer that has the same carb as yours, starts/idles on choke, but does when choke is off (or if throttle applied). carb was cleaned out, fuel line changed, fuel filter changed, but still symptomatic. thank you!
Do ya best, sometimes the carbs are too far gone, it happens to me as well
This carb has one adjustment. I start messin with it around 26:30
Thanx for watching!
@@TheNovaJohn thanks! looks like just the idle screw is adjustable eh. subscribed!
@@seedyeh Yea, newer models are adjustment delete. just sold a craftsman backpack blower, I went over it but informed the fella, its as tuned as its ever gonna get.
Gotta say, although I sold this machine, I will keep another one if it cleans up like this one!
hello, can valves keep engine from doing anything? I have a Black Max 4 cycle trimmer. same engine. It has never run. got it on clearance and cant return it. I have spark, i got a new plug, will not run with starter fluid in the carb. Will not do anything. from what I understand disassembly is required to find timing mark on the crank shaft. I get a little, very littel smoke from exhaust. Any help would be appreciated
1st check compression!!
No compression or very low then ya gotta go deeper
I know this sounds crazy, im pretty sure the flywheel is on backwards from the factory. when the piston is at tdc, the weight on the flywheel is going past the coil, the side opposite the magneto. im going to take it off, flip it around and see what happens. can you please tell me where the hole in the camshaft should be when the magneto and coil are aligned one over the other?
@@TheNovaJohn
I haven't taken that engine apart yet, there should be a key and keyway that will align the crank to the flywheel.
It cant go on backwards as the shaft is tapered but it may not be in alignment!
sounds like your on to something here! Keep going!!!!
the key was shaved off the flywheel. they are made on had to knock the rest out and use an improvised key. running now thanks @@TheNovaJohn
Awesome,, great to hear and thanx for letting me know!!
How many oz. of oil do you put on a 2 cycle motor.
That depends on the mix. most use a 50:1 mix these days. Pick up a container of 2 stroke oil, read the back of it and get a separate gas can for the mix
Extraordinary
yup keep smoking around gas...
The temperature of a lit cigarette is not a high enough ignition temperature for even atomized gasoline. A lit cigarette will certainly go out in a bucket of liquid gas. Citation - 10 years working on fueling systems.
Ryobi 430 slip timeing whst cast problem
bad or loose belt maybe
Those S430 stringers are pure junk.
I have 2 of them, and they both smoke like a volcano.
“Oil smoke “
They have very small crank cases, the oil needs to be changed every year and cant be over filled.. Other then a valve adjustment they work well.
@@TheNovaJohn what is the reason that causes them to blow oil smoke so badly?
Like I said above, the oil goes bad quick, if this isnt changed it gets dirty and gets thin as well or even runs out, then the rings start to wear and it will burn oil.
Its a 4 stroke, are you mixing oil with the gas? If you have 2 that do this, its something your doing or not doing.
@@TheNovaJohn just running straight gas. Does well until it warms up, then it starts smoking.
try a thicker oil like 20w50 and watch the level, don't over fill
I have one leaks oil bad short ignition
Oh wow,,,sounds like it might be toast!
It shouldn't be it's not that old
Well if any thing needs a seal or bearing if I have to I will make my own
Fab fix, top vid
Thanks!!
Good work . Nice bit of kit.
Thanks,,,,, It really is nice,,, I would be happy with it! I almost wanna keep it!!
2.5 oz of oil go in it.
Yea, its like a couple of spoon full lol
@@TheNovaJohn I think that's where Ryobi screwed up. Should have a bigger oil pan. The next goof up is that plastic flywheel. When I ran mine it seems as if the belt wants to come off. Definitely a failure point built into the design..
Even some of the Stihl equipment uses plastic gears
This is a very good and informing video, but to me, why switch this stiff to 4 cycle engines. 2 cycle is much easier to working and, i.e. less moving parts, and much lighter without high level costly engineering. I'll stick with 2 cycle until either they're dead or I'm dead.
Thanks,,,,In a word ,,,EPA, mostly California dictates. Now in Cali they banned the sale of all gas engine lawn machines.
Some say this model is crap, from working on it, seems fine and sounded great.
@@TheNovaJohnthat's because California is full of communist 🤬
Nice video! I dug mine out today mostly because the cordless one doesn't have the umph and there's the sound factor too.
Thanks,,,,,I like these, I call them Thumpers, big engine and runs very smoove!!!
I sold this one,,,,,I would prefer to sell and repair these,,,Its the 1st one I've done..
They are junk
First step: Dont buy ryobi tools…they are garbage at best
I have a few, for the price they ae ok,, I don't have any real issues with them. For things I don't need everyday they seem fine
Mine was free so that price is kinda good.
@@TechGorilla1987 Free is 4 Meee,,,,hey ya cam always put it back to the curb!!
Dude freaking camera angle Jesus
what ya don't like it? At the time I had one camera. Camera gear is expensive! Over the shoulder shots don't always work either. In front there isn't enough room and you wont see what I see. I'm still new at this.
I have ten 2 stroke Ryobi full Cranks. When they are working, they are great. I have a golf course in Mexico and girls running the Ryobi's and after about 6 months max. they quit. I dug them all out the other day and started the investigation, all have bad ignition coils. These trimmers look close to new, and all coils are bad. Compression, carbs, etc. all perfect. The coil to flywheel clearance is fine on all of them except for 3. The fuel filters go bad fast including the primer bulb so make sure you have spares along with fuel line and spark plugs. Another common problem is the crank bearing on flywheel end goes bad and the coils can actually start rubbing on the flywheel so if you see your coil scrapping the flywheel, the crank bearing is probably trash. 3 of mine have this problem. You just grab the flywheel and pull it up and down, if it moves, it's junk. I will say for the money and time mine have lasted; they are worth it. The girls run them full bore/throttle all day long. I run 20 to 1 fuel to oil. 50 to 1, they won't last long.
Anyways, pulled out my S430 4 cycle trimmers. I have one early model which is total junk because of plastic cam shaft which melted. Plastic cam on top of engine, the hottest place, are they nuts? The other has the metal cam and going through it today. They have a common problem with the cam bearing closest to the gear belt drive going bad and the cam/gear drops down making the belt loose and it either skips gear teeth or rides off the gear. Another problem is the engine sucks in oil from the crank case breather tubes and smokes like hell and covers the air filter with oil, and trashes the spark plug fast. Forget replacing the belt, way too much work, not worth it. If the cam bearing is worn out, the motor is junk. Why they don't install better bearings on the cam is beyond me. And the oil pans tend to leak. I will say when it is running it is a great trimmer. Starts on the first pull always. And no mixing gas and oil. And you can't tip these 4 strokes sideways at all, they will start to smoke big time. And you have to store them sitting flat, you can't hang them on the wall or laying on their sides, the oil will work its way into the cylinder so you will have to pull the plug and blow the oil out and refill the oil pan. The girls don't like the 4 strokes because they are too heavy for all day work. The girls have 5000 feet of fence line to weed eat and around many trees and plants 6 days a week. I can't find any of these tiny tiny spark plugs for these 4 strokes in Mexico. Why could they not use a normal size spark plug? come on!! The 2 strokes have a lot more power and RPMs so much faster at weed eating. The chain saw attachment you have to run the 4-stroke full throttle and still doesn't compare to the 2 strokes for cutting wood or branches and again you have to keep the 4-stroke level which is hard to do when cutting tree branches. A neighbor has a diesel string trimmer that has run for years and years, need to find out what brand it is?
Great Info so I Pinned this to the top of the posts!
Almost sounds like we need to run a but of oil in the gas!
All Good to know!
I see these as basic homeowner machines that require yearly oil changes. Since they hold so little oil, it needs to be checked constantly.
For the price, its good power and fairly reliable when used as a homeowner rig.
I love my Stihl! Link Below!!!
Thanks for the Info!!

Got my bought used: S430, 4 stroke running, new fuel line, filter, and plug. Filled it with 40W oil and a dash of Moly which eliminates all wear. I disconnected the valve cover breather tube from the air cleaner because I don't want it sucking oil into the air filter and engine trashing the plug and smoking like hell. Let it run at fast idle for 30 minutes and it pumped out all oil out of the front cam bearing next to belt gear/pulley. What a mess because the flywheel fan blew the oil all over the engine on all sides and top. Belt was running on 1/2 the cam gear so pulled belt off and sure enough, cam bearing shot/could move it up and down a lot. So, engine is junk. Sad because the engine runs fantastic and smooth with great throttle response and power. Unit looks brand new but junk. If I get a new one, I will run 40W and some Moly in the oil which will guarantee 0 wear of anything. Then I will have a good machine. I like the Honda trimmers but not the price. This S430 must have run low on oil before I got it. Seller on eBay said refurbished, Ya right!! Ordered an ignition coil for my 2-stroke full crank string trimmer for 15 bucks and free delivery to Mexico which is fantastic. Will do a test on the new one with OHM meter before I install to get readings. If it fixes the problem, will buy 6 more and get the rest of my 2-strokes going again. Wish there was a kit to fix the cam bearing on S430, I would do that, but I am not drilling out the cam bearing hole to do it, would need a precision reamer to make it perfect and a jig for perfect alignment which I don't have either.
@@grantmx4742 Really is a nice machine but regardless of moly or any nice additive, they wont live for too long anyway. Its a complicated machine. These just aren't made for any abuse. If in good shape and maintained it will give long life.
I wouldn't disconnect the breather hose. That small amount of lube it will suck will help it to live longer, plugs are cheap, easy to change and clean but if it trashes the engine for the sake of the plug?
@@TheNovaJohn Thanks for the reply. I had no choice but to disconnect the vacuum line from valve cover to air filter housing, it sucked in so much oil it was running out of air filter housing and the engine smoked so bad it clouded out my total back yard. Neighbors thought there was a big fire going on, hehehehehe.
Thanks for all of you demonstrations,I have learn a lot from your demos,thanks.
