Chainsaw Repair

Here is a picture. I hope it is good enough. The new piston has a shorter skirt so the wrist pins are not setting at the same level.

The difference in skirt height seems considerable. I'd make sure it doesnt free port before doing a complete assy

i thought the skirt was a little short from the first pic.
i notice short skirts. especially when they're real short
on a serious note, i would really make sure it doesn't free port. the cylinder looks quite good (on the outside anyway ), maybe it might be worth it to get another piston. check for free port first.

Here is a better picture of the pistons. I have them connected by the wrist pin. It does not free port.



I did not do anything to the muffler yet but a gasket match.

The exhaust side of the cylinder

I just did a gasket match to it.

No After picture, I forgot to take one.

The intake side

I just cleaned it up a little.

Before (really bad picture)



After

Could I have opened the left side up to match the right side?



I have it running. I used it just a little this afternoon. I had to put a 20" bar and chain on it because I don't have a 16" chain yet. I want to run it a little bit then I might do a muffler mod. Thanks for the help.

I ran the saw a little today. It does not have the power I think it should. Maybe I am expecting too much from it. I checked the compression and it only has 120#s cold. should it have more?

Run the snot out of it .It should seat in the rings and the comp should go up .

FWIW it took me the best part of one summer to get the rings seated on an 038 Mag  I rebuilt .Simpley because I was cutting down from a 10 cord pile of oak at 10-15 minutes run time at a time .Now once those rings seated the improvement was dramatic .
