1956 Farmall 400 gas, recently purchased with rebuilt engine.
Spent the holiday doing tuneup. Points, plugs and carb. Set all to spc per owners manual. Distributor seems tight with minimal sideplay. Took the cover plate off the governor for a look and all internal was clean and appeared to be in good shape visualy.
After tuneup, tractor starts fine, almost immediately on first turnover and ran steady with no flutter and clear exhaust. Tried to check timing. couldn't get the low idle below 600 rpm (looking for 450). tractor cuts out at anything below 550 and stutters bad between 550 & 600. Also, could not get high idle over 1350 rpm. (looking for 1650) I made the adjustments to the idle screw in small increments and worked the throttle after each adjustment.
Not getting the motor to idle slow enough to check timing without the advance kicking in I checked timing at high idle looking for 25° advance. it was relatively close but fluttered about 5° or a bit more ahead and behind the mark. The flutter seemed to be consistent going from just behind to just ahead regularly. Every so often it would hit the 25° mark.
Took the tractor our for a workout with a 7' brushhog in high heavy grass. In first and second gear both motor seemed to pull well under heavy load and the governor seemed to be working. Temperature stayed in the low side of the "run" section of the guage after an hour on a realatively hard pull.
Any ideas on the low idle and high idle issue? I am stumped at this point.
