Yep that's the one that actually is 3.0ci/49cc.  Great little saws.
-Aaron

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.

Well the 3.7 arrived today :)  The saw has  definitely been through some wood in it's days but there's absolutely no signs of piston(2 thin ring,C/B  or bore wear or scoring but will need re-ringing as the compression limit was 110. The power head definitely feels better and lighter than the 5020 I have. Gonna get it cleaned up,parts ordered and search this form for the finer details of rebuilding and modding .

Ripper on page 5 of the Poulan forum here there is a thread called "all hail the 3400".  It has some good info on modding these saws.    I found the information there pretty good.

I was looking at the part numbers for the 3450/3750 and they do not share the same number for the 3000
So I would say the crankcases are different.   How they are different I do not know.

Muffler is smaller on 2800-3300 crankcase is wider on starter side front.  3450-3750, etc muffler is wider than 2800-3300.  Crankcase muffler opening is (starter side front) wider for larger muffler.  Clutch side of crankcase appears to be the same on all models. Starter side is diff. on 2800-3300 than 3450-3750,etc.

C4F, I've weight the 3.7  4 times and every time the weight with B/C dry comes out to 14.8lbs. I immediately noticed the differences when picking up just the power head. It has a plastic chain adjustment cover,so that there may lay the difference.
