I recently purchased an Allis B which seemed to be running extremely lean (sounded like it was under heavy load even at idle) due to a bad exhaust manifold. I replaced the manifold and gasket and it's better, but still sounds like it's working hard just to run. I think the carburetor is fine as it's been gone through. I'm thinking the problem is timing. The original magneto was replaced with a rebuilt IH (appears to be an H4 type, but I'm away from the farm right now so I can't post a picture). The engine runs "best" when the mag is rotated all the way "in" toward the engine. It would be really great if I could rotate it even further, but of course I can't. It only strains harder the farther out it's rotated. So here are my questions:
1. Is this mag even compatible with the Allis Chalmers B? I can't seem to find it anywhere when compatible mags are listed. When it's running, it runs very smoothly, doesn't miss or anything, just sounds and blows exhaust like it's really working (especially compared to my other B). Exhaust is clean, no smoke whatsoever.
2. Is it possible or likely that the gear mesh is not sync'ed up correctly internally? Since I'm out of adjustment and turning the mag "in" only helps, can I just adjust the gears one tooth?
Thanks in advance!
