Some info I have saved in the poulan 4000 thread.

4000 bore 49.2mm

3700 47.7mm

3400  46mm

The 3400 run around 125 to 135 psi.
The 3700 will run around 150 to 160 psi
The 4000 is the same as the 3700 they both have two thin rings and the only real difference is in
the bore size as far as compression goes.

I have seen the exception posted where someone got up to 175 psi on the 3700 and 4000 models.

Any other info just add to it.  Thanks

New owner put his gauge on the 3.0 3.4 and 375 to check psi. I never did as they felt normal ranges to me.

3.0 3.4 135psi

375 150psi

Good numbers for both.  Doubt they pushed any more than that when new.
-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.
