Back ground, the saw came to me after a customer picked up from another shop. Was taken is because it was idling poorly.

Tell me what ya'll see.

I'll try and post up better pictures later. This particular camera sucks

BTW, the cylinder has no scratches or marks at all.

missing rings or broken ring?

Effect, not the cause.

OH Man!!

Where did it go? They didn't put it together that way??? DID they???

some debry dancing around on top of piston ....and finally spit out...?

 

[kevlar]

piston on backwards-(pics make it hard to tell)

Yep, looks to me like piston was on wrong way round.

Actually, without being able to see the top of the piston, not really a fair question.

Piston is on correctly, it was the original piston.

The top of the piston shows 3 indents, inline with the 3 gouges. Those indents happen to match up to one of those little orange handle still screwdrivers. Best I can tell someone attempted to use it as a piston stop...

Customer claims he never took the muffler off. Never attempted to work on the saw himself. The cylinder had zero scratches on it...which tells me the saw was not running.

It's back together now. New Piston, the clutch side crank seal replaced, looks like that was the original issue. I did need to touch up the top of the exhaust port...surprise, surprise it had three indent...

I'll toss the piston in the truck tonight and bring it home. Post up some better pictures of it later on.

Friggen hacks...

Let me get this straight. Are you saying that someone used a little orange handled stihl screwdriver throught the exhaust port as a piston stop?

That's brilliant!

Better yet, they sold him a new P & C after doing so.
