You guys got your wish. I've definately been handicapped here. The P&C are significantly scored. What's amazing is that it started right up and ran and pulled 160 PSI compression. Don't ask me how.
As you know, these aren't chrome lined jugs, and shouldn't be honed. I had no choice, and nothing to loose. I sanded the piston and ring as well. I'm going to make this thing run! I'm just not going to guarantee how well or how long, lol. Yes, I'm even going to port this piece of trash
These pics are from AFTER the cleanup
The Poulan Pro's do have chrome lined cylinders, that's I guess what makes them "Pro's".

I'm tellin' ya, the more I fool with these little saws, the more impressed I am with them.
You are beginning to act like me now Brad!
Smoothing up and running some old junkers!!!LOL
That saw is pulling nicely!!!
Mike
The venturi on the carb was a tiny little .315". Yes, you read that right. I opened it up to .400". I left the fresh air venturi alone. It's quit a bit larger. I didn't tach it before, but it's now turning somewhere between 13,000-13,500. Throttle response isn't that good, but is no different than before opening up the carb.
Brad your saw looks strong! Did you happen to check you're ring end gap?
My saw is only pumping 125 psi, and I know it's the ring, the gap was pretty huge. Any of you guys have any extra rings laying around?

I did not. Any idea what RPMs yours is turning?
About 13,000 I saw 13,200 but that was just too lean.

One of you please be sure to bring your tach tomorrow, I'd like to check mine.
The carb is the bottleneck on mine too.
The engine is doing all the carb will allow.

NM, I found it. Yours has excellent throttle response.

Guess who's back
put on a carb from a bigger saw.......... i did
Yup I have the H screw turned pretty far out, way more than normal. I'll make sure to bring my tach.
Here's what the port timing was on mine stock.
Exhaust - 110
Transfers - 127
Intake - 66
I took the intake all the way down to 80. That may have been too much for it. But I don't know what these run like stock. I raised the exhaust 4-5° and the transfers a couple.
