Looks like it ran on a dirt track?
We should share what we know... someone may learn...

Good candidate for building a saw with a front-tank carcass.  200, 250, 1-43, 1-50, etc.  That's what I'd do..
-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.

That'd be too easy to spot.

Anybody that knows Macs can spot a Super Series engine where a non Super Series should be.  The FW cover gives 'em away...

As I said knowing interchangeability sure helps too

As I recall the 49's had a pretty good record in whatever class they ran in back in the day .

I have the bones of a super 44 Dan Henry gave me that I hope to resurrect into a vintage hotty whenever I find the time .Just a toy more or less .
