Those of you that have been helping with his I have some questions. I removed the piston out of the saw I have and found the rings to look dark and also noticed the rings still have (rings) in the wear surface. Tonight I tried reinstalling the piston and had no issue with it sliding in after I lined up the pins.
So after knowing it was not difficult to reinstall the piston I took the one out of the donor saw that a AS member sent to me for the use of the fuel tank.
Here in the picture is the difference in the rings. I am thinking that my saw has had new rings installed and that is why maybe that compression was on the low side (90 psi)? As they were not worn in yet. This saw came to me in parts so I do not know the history on it. It was quite clean as in cleaned for a repair but case was broken and tank leaked fuel.
Does this one ring look like it would if it were new> the cylinder on the inside is smooth.
I am thinking the possible reason for the saw running so poorly was the crank seals are hard as rocks and it was not pulling fuel properly? Just trying to figure out what way to go with this.
It seems to me there is nothing wrong with the rings as they look new and not run beyond me starting a last week.
