Nylons anyone?

Piece of race/cage I am imagining. Fell outta the bottom end when I smacked it a few times.

And some debris on the inside of the screen where it looks like the carb body/throat plastic has a teenie-tiny gap in the corner and allowed material through. Looks like a pinhole when pushed snugly in place. Note the debris crammed in the cylinder top.

Also, the needle bearing on the clutch froze up whenever it seized. Odd. It had been greased less than five tanks prior.

That was a new plug, also, less than twenty tanks.


This saw had been running fine and had been retuned within five tanks of this happenening. All relatively same elevations and temps. Not straight gassed.

RIP, Althea

What make model of saw? What seems to be the problem? Your plug is white, been drawing air through crank seals?

It's a late 2016 or early 2017 562xp (think 2017, but would have to check the tag)

Has run flawlessly save for a few minor things. Fuel hose clips on the air-filter mount weakened and let a line rub against the hot carb. That was probably 80-100 tanks prior to this failure.

Saw "rattled" ever so slightly from the clutch since day one. Some of them seem to do that.


The plug is actually tan/caramel, not white.

Piston is in good shape with minimal wear scoring to the cylinder. Rings were about ready for a change, but not overly worn or broken in any way.
