As with all engines, you need spark, fuel and compression. If all three are present it will run, if any are missing it won't. When you try to start the engine, does it turn over at normal speed, as if it is trying to start, or does it spin a lot faster or slower than you might expect? If it is a lot faster, you may have low compression. If it is a lot ...

Pull the carburetor and disassemble carefully, clean it and the main and idle jet passages with carb cleaner in a spray can. More than likely bowl sediment go knocked loose in the move and is now partially clogging the idle jet. What I think is happening, the engine tries to idle on the idle jet but it is not getting enough fuel to maintain the idle, when ...

Your strategy should be to get the dealer to fix your bike. They should be able to test for a parasitic battery drain by putting a multimeter in-line between the battery feed and the terminal (that's a test you can do yourself as well). Small problems can develop into big problems over time, get it dealt with now while its still under warranty. Installing ...

Turned out to be the fuel pump. It's getting replaced on warranty :D

It's possible for the rings to wear and loose tension, with the piston and bore showing little sign of wear.In that case putting in new rings will probably revitalise the engine.Symptoms of that would be low compression,lack of power,but the saw still running and the piston / bore being on good condition. But more common,or at least total failures,usually ...

Some people don't know which part was bad,so they prefer to buy a whole chainsaw parts,after all,a whole set including Cylinder,piston and rings are not expensive.I see,Cylinder Piston Rings Kit online For Husqvarna 357 at enter link description here is about $22.50-a price to please almost every pocketbook.Not sure the longevity.

Normally with those chainsaw motors the problem is wear on the cylinder. If it where a car, you´d do a new honing of the cylinders and put in oversize pistons. Given the prices of chainsaw spare parts this is not economical, so you just replace the whole set.

Some small engines have what is called a compression release and is part of the camshaft. What it does is release some of the compression during starting so the engine can spin up and start running. Then, after the cam starts spinning at operating speed, the compression release mechanism swings out of the way and allows for full compression. It is ...

Since the blade is balanced you probably don't want to use lock washers, but you can get away with LockTite or some othe thread lockers. Just be sure that the one you use is reversible. Some will make it so the blade never comes off, even when you want it too. Generally speaking LockTite Red is the permanent kind. You want blue, or purple LockTite. There are ...

I don't disagree with @Moab. I would add, that sure sounds like a positive feedback on the air vane that controls the idle speed. The air vane is driven by the flywheel vanes. If the vane gets bent, or a spring gets disconnected, the whole thing goes in this fast slow oscillating control loop. If you remove the cover you should be able to see the ...
