Have a M that has been setting since 1979. Had fuel tankcleaned and sealed, Manifold machined, new sediment bulb, new plugs and points,and generator rebuilt. Tractor starts easily but will not idle unless choke isat least half to 3/4 and Air Jet completely closed. Tractor will run fine athalf to full throttle without choke. Looking for some help with diagnosingthis.

your idle air screw might be out of adjustment. you might also want to check your timing.
