Would anyone know if its easy replacing the clutch in an Echo CS-370 or should I have a Echo dealer do it? I think it seized. I can't pull the starter cord. Its about 7 years old, Thanks

Sounds much more likely that the motor is seized and not the clutch. You should still be able to pull over a saw with a stuck clutch specially if the bar and chain are off.

Brett's right, Jeff's wrong!) a clutch is very simple to change (and cheap) but it should still pull over with a bad clutch, did you try taking the spark plug out then give it a pull? That'll narrow it down.

Took the plug out but still could'nt pull the cord so I'm guessing the motor seized.

Gas mix

Could be too much or too little oil to gas. Too much burns hot and can seize a cylinder. Too little runs dry. Also, especially in hot weather, keep the chips from your cooling ports or covers.

Update on Seize!!

August 6 2017, 11:57 AM 

Got my saw back and they did say the piston was seized up in the cylinder. Told me to use an Ethanol additive and a higher octane in the gas I use. Been using 89 octane for years but I don't see using an ethanol additive in the Echo manuals. I will start adding this to my jug but wondering if it will loosen up any gunk in my older saws!!

Hey Dean, thanks i was curious how it turned out. I was stuck on 89 octane for long time but now if i understand correctly, the ethanol is around 10% on average and what they tell me at the saw shop their seeing more & more carb problems related to this, and a higher octane gas helps offset that. But seized piston actually sounds more like somebody forgot to put oil in the gas. I happened upon Denny Beach one day (at the vous) with a seized up saw and we figured out that was in fact the problem, forgot the mix...! see can happen to anybody!
