Older saw ran a lot slower speed, high torque, compared to today. 

I don't know what kind of chain we had! Somebody else sharpened them. Did not become 'chain aware' until the 90's!

I really like Oregon 76 on my 41cc Homelite Super E-Z's.  Hoping to get some more.  It's a great match for those strong little 41cc saws that act like they're bigger.  .325 pitch chain sized cutters (sharpens with a 3/16" file) but on a lightened 3/8" pitch chassis with full size 3/8" pitch drivers.  Will try some on my 36-46cc Poulvarnas too.

1/4" chain was released for little saws (Mac PM6, Homelite XL, Poulan XXV, etc) long before 3/8LP was introduced.  I don't like it.  Too damn hard for me to see and sharpen.  Also a zillion cutters to sharpen, even on these short bars.  It is really smooth for carving however.  I have one saw (Craftsman 1.9 branded Poulan 20D) that will remain 1/4" pitch for carving shenanegans.  Every other 1/4 pitch saw of mine either gets sold/given away, converted to LP, or parted out...

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.
