Looking for any advice or things to look out for, replacing the piston on my recently acquired 655bp. It is indeed a bp, pulled the muffler and can clearly see the boost port on opposite side of the cyl. But was noticing that it had a standard piston in it. From what I have been able to gather, early BP's were this way. Latter ones utilized a piston to take further advantage of the BP's function. Open skirt on the piston on that side. I have got a new piston here for it. Just not sure when I'll get started on it.
I have not even started the saw. And probably doing more work than is necessary, for what little gain might be achieved. Don't know. I figured what the heck. If thats what they finally came up with for this saw, then I will do it also.
These Pioneer based saws are new territory for me. So any things a newbie needs to know about these when dismantling or putting back together would be appreciated.
Gregg,
