- In this video we will look at a Husqvarna 435 chainsaw with a customer complaint that it starts hard. Follow along and see why its not always about fuel, spark and compression. #smallenginerepair
Good one, Scott! I also was guessing clutch issue like others - overheated, stretched springs.
The lesson is, never, EVER, assume the customer knows what they’re doing! 😉🔧👍
It just looks better with the factory bar anyhow, nice job bud, thanks for bringing us along!
Thanks for watching!
Fantastic video. Glad to see two videos. You probably figured I’ve been in/ out/home and never saw the technique of back blowing through the muffler. Don’t have money, but wish there’s a way to help you. Take care.
I ended up replacing the worm gear, bearing, and clutch on my 435. My issue was chain turned all the time at idle. I figured clutch springs. When I inspected the worm it was damaged.
Thanks for another awesome video Scott!
Thanks for watching!
Great technique blowing from the exhaust side to clear potential debris from the intake side safely. I wonder, though, about blowing carbon bits from the exhaust. Do you think they would also blow right through or is there a chance one might get caught in a transfer passage? I might pull the muffler, just in case.
Certainly anything is possible but remember the engine is creating pulses in and out of that muffler. If there are carbon bits loose enough to move under the lower air pressure I'm using then they probably can already move back and forth. I've seen broken pieces of muffler baffle get pulled in so the possibility already exists to pull small carbon bits in.
Yep have to pay attention! I can't believe the stack of straight gassed saws down at my Husky dealer! Well done!
We see it too but not a lot. When we sell a saw to someone we are not familiar with, they get the whole speech and demo. If it does come back scored its because the lent it to a neighbor
Broken Clutch Springs Is Usually The Culprit 😩😩😩 Have Not Seen That Issue The Bronze Bushing In The Worm Gear I’ve Seen Wallow Out I’ve Seen The Customer Mix up Bars n Chains a Lot Great Catch And Repair Diagnostics 😀
That plastic worm gear doesn't even have a bushing. Its just plastic so sanding or filing also works.
That's a pretty smart move blowing the air gun into the exhaust to keep the gunk out
Thanks, I've had good luck doing it that way.
Enjoy your videos . I get a lot of info . Thank you for sharing your knowledge.
I enjoy making the videos. Thanks for watching!
I like that little inspection pen light you use. Where does one find that particular one?

Did you consider replacing the sprocket to match the pitch of his new chain and bar?
Husqvarna only offers this drum in .325 so there was no switching it. I suppose I could have researched if the aftermarket offers one in 3/8 but its been my experience that converting it will only create more confusion in the future. Because of the added cost I'm sure I would have called the customer before replacing his new bar and chain.
Hello, scott! I'm rebuilding a 550XP Mark II, and the head on one of the front muffler bolts is stripped, do you think a vice grip would work to remove that? I was considering squaring the head with a file so I could get a proper wrench on it, but curious to get some input before I actually move forward.
I guess first choice would be one of those RBRT bits. second choice would be some form of what you said. Third option would be welding a nut to it. Fourth options requires you buying a new muffler 😞
Love your videos you’ll get the job done😊
@@roccozarcone4393 Thanks for watching!
Now that was something.
Question...So, most, if not all, 2 stroke engines use a "short to ground method" for turning off the motor. It seems that when the ignition coil no longer works, the thought which comes to mind is,"It worked the last time I was using it."
Yeah. Of course. And the last time you turned it off the coil was shorted to ground.
A spark plug gap does have resistance when sparking. Grounding the coil directly...well not any worth mentioning. Maybe that burned out the coil?
I choke stop now.
Well that comment is now renting space in my head. I'm gonna give that some thought
Love your videos! 😊
Thanks!
My brother got me a 435 about 5 years ago , used it for about 4 months and one day it was running I shut it off went to fire it up and nothing. I pulled and pulled and pulled and primed and pulled and made sure the spark plug was dry and not flooded and nothing, It has great compression pulls smooth it was brand new out of the box but it was purchased on amazon as a gift and I didn't have the warranty. I pulled until I broke the pull cord and said fk it. Put it on a shelf in my shop and there she sat. Well last summer I decided to try and get her running but to no avail. I put a completely new carburetor on it new plug new filter checked all the fuel lines for leaks put fresh gas in her and checked to make sure I was getting spark and was. Put her back together and pulled until my arm was to tired to pull it anymore. So back on the shelf she went. I tried giving her a blast of starting fluid primed it welll and still nothing. She pulls smooth sounds like she wants to start compressoin is good but it just wont start. And ideas on what it could be thats keeping her from firing up? Its had less than 40 hours on it and the nearest shop to fix it is 200 miles away and I don't want to make multiple 400 mile round trips if I dont have too. Any idead would be very. Much appreciated. Thanks again.
First make sure the cylinder is clean and not scored. If the cylinder is wet after trying to start it then check the flywheel key. If the cylinder is dry then check the spark arrestor screen. If those check out ok you may have a bad ignition module.
Oh I forgot to add the possibility of a big air leak.
@@TheGreasyShopRag Thank you I will give that a shot and let you know if that worked.
Well I pulled the flywheel and the key seems looked fine its definitely engaging the motor and I went ahead and changed the fuel lines to make sure there was no leak, I also over primed it with the bulb and let it sit for a while and then removed the gas cap and there was pressure in the tank and fuel was in the combustion chamber and on the plug so I know its getting fuel. I gave it about 10 good pulls and and it was firing bud not just for a second then I got a loud pop like a back fire. Its a new carburetor oem and im guessing they tune it and since I haven't been able to get it running I haven't tried to tune it but I'm wondering if that might be the issue?
@@tristinstorm5858 It could be the issue...or it could be terribly flooded. Hard to say without being there.
What’s the process for the clutch removal
Turn the clutch clockwise to remove it. If you don't have the special tool then you will need a punch and hammer. If the clutch is on tight then you may need to lock the engine. This can be done by putting rope in the spark plug hole. You're best off searching for a video that shows this process because you don't want that rope getting caught in a port.
So with a gun how would you safely loosen it to take it off, and tighten it to reinstall it?
@@israellopez9147 It sounds like you don't have any experience with an impact gun. If thats true then I recommend getting a feel for what the gun can do by using it on something else first. Maybe lug nuts. Having said that, when you use an impact wrench and it doesn't break the clutch loose it will turn the engine over. If the kill switch is on then the engine could start. Also, if you rattle on the impact for a long time you could cause other damage in the engine so be careful. You don't have to rattle the clutch back on because it will naturally want to tighten when you cut.
Grease on the chaser helps
Thats a popular method but I never fit in with the popular group. Thanks for watching!
How many depends are u allotted per day ??
Are you getting a husqvarna neck tattoo??
@@jonathanfierberg3807 Thats a crappy question to ask.
