I had it once with an old fuel line. It simply dissolved from inside and left a bunch of crap in my carb. Of course, the fuel pump was messed up too. So I took all the shit apart to clean it thoroughly with brake cleaner and compressed air. That solved the problem. One sure diagnosis: If you have to hit the primer bulb repeatedly, it's a faulty fuel pump. These diaphragm pumps can easily fail and they're not happy about any crap in the fuel. I have a clear hose running from the fuel pump to the carb so I can watch if there is fuel or not (or air bubbles if there is a leak). My fuel filter sits 5 inches from the tank. After all, if there is crap in the tank you do NOT want that shit into your fuel pump and from there to the carb. It will contaminate the whole system and make you take all this crap apart again. So stop any dirt from entering BEFORE the fuel connector on the motor.
You are a better man than me……..about 1/3 of the way in my trash can would have been eating that motor for lunch. lol. Keep the faith brother……..the saga continues.
Had the same cold start issue with my 1975 4 hp Lightwin after carb clean, new fuel pump and igntion parts and recoil repair. Turned out the choke knob was upside down so the butterfly was not fully closing to draw fuel into the reeds. Flipped the knob and the butterfly closed fully and engine now starts on 2nd pull. That ridiculous recoil doesnt give much pull to begin with so I use the rope sheave and pull over manually. Good job sticking with it!
Hey. Thanks for tuning in. Sounds similar to what I just went through with the remote control on my 60 Johnson. After testing everything ignition, 5 hours later I find the plug came off the powerpak! Hahaha Brutal! Thanks again !
Thought it was the fuel pump. Had a 57 merc that I saved from the scrap metal yard. Guy said he couldn't keep it running. I took the fuel pump apart and it looked good but the service manual showed a 3rd gasket that was missing. Bought he kit and it ran great
She's a temperamental little thing that's for sure, I think I'm going to make a batch of that rip roaring chili that I seen. Your video looks delicious and I love chili!
The intermissios l love it "Chuck Wholery & The Love Connection We"ll be back in 2 minutes 2 seconds❤"✌ Motor sounds great! Hey do you run ethanol free gas for your motors?
Very realistic video as things do not always work out easy ! For honing, I prefer those ball-shaped honers because they don't catch on the cylinder ports ... well for amateurs anyway. For me, there is nothing wrong with drill-starting all through the tuning process as it sure lowers one's frustration level. I find that fuel pump related or air leakage issues are at the root of most bad running small outboards. While I've got your attention, how about making a video about fixing a leaking top crakshaft oil slinger as I couldn't find any. Regards !
Thanks for tuning in! I prefer the straight edge hones. Mmmm. The dingleberry hones won't show imperfections on the cylinder walls if they're out of round because they flex and will catch the ports, but great for a quick cleaning. But everyone has their own preference. Thanks again & Stay tuned !
Watched you row the boat, the other day i was out in an unknown motor i had running at home 20 hp merc 1979 got it fired up first time on the overfull river it went a thousand feed then would die, I was thinking about you being stalled, did that same thing like four different times, i figure with my limited knowledge gas tank vent?
Good job Now just put some time on it under load - Get carb right & itll idle loke sewing machine - I have several of the older 3hps w/ weedless gear case - Great motors Last forever Good little kicker motors for trolling & will go to China on teacup of fuel- I have one '63 longshaft that needs all new tune up parts but the short shafts will troll well on 20" transom - Hollar at ulatr.
If i hear I need a little more pull on this rope im gonna fly down and fix it myself 😅 When they look great thats usuaully a sign they ran like crap or had problems.
Have a question well I was like you today out on Seneca lake stranded 5 miles from were my parents lake house was. I just thought it was the shear pin and it was the shear pin did break. Fix that tryed it again not good. I think got bigger problems in the lower unit. I am going to check the oil level first. If that checks out I might have to look at the gears in the lower unit. Funny thing is my parents lake property is all ready sold they have to be out by July 30 2024. I probably will take the motor with me and look at it and get it fix. What are your thoughts on the problem thank Kyle own a 1969 Johnson outboard 25 long shaft
Hey. The 69 25 has the split gearcase which is much easier to open up and work on. But first thing I would check is the shift rod linkage. On the side of the exhaust housing is that little plate with the 2 screws, open it up and you'll see where the upper & lower shift rods are held together by a brass connector with 2 screws in it. If the shift rod is slipping in the connector it won't go into gear. It's usually the upper rod that likes to slip. Also check the linkage at the shifter handle, I believe there's an adjustment on that too. If everything is shifting fine you'll have to open up the gearcase, usually its a worn "clutch dog" shifter gear. But you won't know until you open it up. Go to marineengine.com and look up your year/model. Check the schematics, you'll see how its put together. If you need parts check ebay for some good used parts. Just use the part numbers to search ebay. Good Luck!
My humble opinion is that you can't get that carb set at that idle speed...you are still getting enough DRAW from the pistons to get gas from the high side...edge her down and set low speed as you go. Opinion 2....LOL....you got a tiny reed valve leak.
And you've been talking about that string not being in tight enough. Get more pull, looks to me like you're getting enough pool that flywheel's turning pretty quick should start that little engine but maybe it's just time to fix the rope. Get it where it needs to be. I know sometimes it's you just don't want to do things. You know I'm the same way
@@THISOLDOUTBOARD1 I think I used 2 sets of vice grips on the one I worked on one set of grips on each side of the assembly to keep it from flying apart.
Did you have the fuel tank sitting on the ground? A weak pump isn’t going to pull gas vertically. The tank should be relatively level with the motor. The pump is probably ok but it won’t lift gas off the ground. As far as using the drill, mine will only start with a drill when it’s cold, so I just carry my cordless drill with me. I only need it for that first cold start, after that just a short pull on the cord is all it takes.
If it was me and I was questioning the pump. I would raise the gas tank and let gravity feed the fuel system. I doubt the motor is designed to pull fuel that high.
It's the same diaphragm pump as on many Johnson/Evinrude. Mine is a 9 1/2 HP Evinrude Sport Twin and will happily pull fuel from my tank that sits about 50 Cm ( 19 Inches) lower than the engine. Of course, these small pumps have limitations and one should make it as easy for them as possible...they'll last longer that way. :)
I love will it run videos! I sit here and cheer, out loud, for both you and the motor! lol
Hahaha! Thanks for tuning in!
ABSOLUTELY loved the show man! You're like an outboard wizard or something! Great job
Hey. Thanks I appreciate that! Stay Tuned !
This reinforces the lesson I was taught years ago............ Don't cut corners on fuel pumps or primer bulbs. Thanks for another great video.
Thanks for tuning in!
No doubt my mind, I know you will get it the way it needs to be. You are the man. Keep up the great work. Love your vids!
Thanks!
These are the best type videos you do its very entertaining to see what the problem is
Hey. Thanks for tuning in!
Mean little 4 horse Johnson awesome 👍👍👍
Thanks !
Your work and knowledge base are admirable, thanks for the enjoyable video.

Great, New is not alway good! Good find...Always good to see a "little Johnson" running.!!

She sounds great when she's running
Thanks for tuning in!
Shoutout to the outboard gods
whas uuuuuupppp!
That’s a great job with that 4 hp Mr Mcguyver you didn’t give up and now it’s staying on. Thank you outboard Gods

It always seems the last thing you look at is the cause of the problem. Take care and keep safe:)
Cool! Good video 👍

Aw yeah 👍👍👍
Thanks again !
Nice music this is outboard music 😂😂👍👍
Thanks for tuning in! Thats my theme song!

For rings on these older motors where they are NLA I've had decent luck contacting Hastings Rings, might give them a try.
Thanks for tuning in!
Cory must be happy you done a awesome job again that 4hp sounds great catch you next time 😊
Hey. Thanks for tuning in!
You put a lot work in that little motor great job see you in the next one 👍🏻🤘🏻
Thanks 👍
Primer bulb and tubing deteriorating? Fuel pump? 😢 Carb settings have to be spot on. It's alive !
Thanks for tuning in!
Whew!
Hey. Thanks for tuning in! That's what I said! Hahaha
thats how my 1985 2hp is tiny little water outlets
👍
The intermissios l love it "Chuck Wholery & The Love Connection We"ll be back in 2 minutes 2 seconds❤"✌
Motor sounds great!
Hey do you run ethanol free gas for your motors?
Thanks for tuning in! No I use the cheap stuff!
hope next 4 hp video the starter rope is proper couldn't notice anything past it.
Thanks for tuning in!

Hey Jack. Thanks for tuning in. China on a teacup! Hahaha Luv That! Thanks again & Stay tuned!
I'm curious about what the compression is now.
Hey. Thanks for tuning in! I haven't checked it since it ran. I'm curious too!
U need to try and get a new primer ball and fuel line brother
Thanks for tuning in!
If i hear I need a little more pull on this rope im gonna fly down and fix it myself 😅 When they look great thats usuaully a sign they ran like crap or had problems.

Yep just went through the same thing with a generator. Plus it had a chitty Chinese carbs on it. No more black chunks. No hope for crappy carb tho.
