Re: mac 1-40 and 250 bar sizes

aaron, VERY helpful. thanks much. one question though.

you stated: 
"Late style inner  bar plate on the left.  Early style McCulloch inner bar plate on the right.  Notice the narrower, higher placed oiler slot on the early plate.  You can also see that the early plate oiler slot lines up with the outer hole on the bar tail of this early style bar.  The late style plate oiler slot lines up with the inner, adjustment pin hole in this bar (and NOT the oiler hole)."

the "higher placed oiler slot" is on the left plate in the pic.
so, is the left plate the late or the early?
i think i know but, as always, my pea brain requires verification.
thanks again,
jerry


This picture?



Early on the left.  Late on the right.

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.
