Reeds and the long stroke to me explain the torque of these in the cut. 1.562 in. (39.69mm) stroke
bore    2.066 in. (52.48mm)   compared to the 505 2083 82.5cc  54mm bore and 36mm stroke    almost 3.69mm more stroke for the 8500  :P

Interesting. Says    Poulan Lime Green and Black in U.S.   Orange and Black in Canada

Tim your green black 8500 you found for $100 was from Canada?

Piston pics look good to me.

Did say it smokes when start but he thinks it is just tuned rich.   Makes me wonder if the pto seal like Aaron said or governor in carb or just the tune.

Yep that looks good to me too.

For older saws:
Tune the H side so that it 4-strokes (burbles) at WOT unloaded and just cleans up when under load.
When you lift cutting load, the saw should immediately revert to 4-stroking.  Fine tune the transition point for the wood you're cutting.

With the carbon inside the muffler can I'm thinking it may be eating a little bar oil.  The piston looks nice and wet, despite sitting for a long time.  That to me says that he ran decent oil and tuned it properly.  These saws like to be tuned a bit fat, especially when running longer bars. 

Some carbon on the piston skirt too.  May also point to some bar oil going through the system.  No big deal, and to be expected with the age of these saws.  Rubber parts don't live forever.  If a person really didn't want to replace the PTO side seal without knowing if it's bad.............they could mix some automotive fluorescent die into the bar oil and then run the saw for a while.  Open the muffler back up and shine a black light in there and the goo should glow if bar oil is present.  I replace the seals on my saws before running them much as a matter of course.  Cheap insurance. 

The PTO side seal is a bastard to get over the step in the crank.  Lip likes to roll under and shed the garter spring.  Last one I did I used the conical seal guide tool meant for installing seals on a Husky 285-2101 series (and 181-288 series plus 394/395).  Much better.  Poulan did sell a conical seal guide tool like this for these saws (and one for the 3400-4000 and another for the 2800-3600/etc).  I've tried ordering them without success.....

Yep all the 8500s I saw in Canada were lime and black. Very strong saw, my brother still has his with a pipe he raced in the 1980's. He had the pipe built by Wolf Performance in Ontario. I believe EHP worked there at the time.

I really wanted one for aa long time to go with my 4200.  Since it would not be a saw we would use just going to build a Husky 2100 i've been collecting parts for.  If I didn't have so much in it I wouldn't even fool with it.
