Chainsaw Repair

It wouldnt matter to me which runs better . Because the PP475 pistons are NLA and I was looking for a donor piston. 

I passed my NOS 475 p onto Roger because I new he was more of a collector. Me as long as the saw runs good I am happy and found a piston easy to get for the 475 saws.

The 064 pistons work in these too.  If you must have windows. Little more pin to crown height too.  Just need to open between the pins some like I did the 066 piston in the 505.
