Hi Allis Guys,

I have a 49 C that I'm restoring. I have completely rebuilt the steering sector, the front pedestal and hubs. Recored the original radiator, New rear wheels and tires, All new brakes, New clutch and release bearing, As far as the engine goes I have replaced the cam bearings, rod and main bearings,new pistons,
sleeves and o-rings, head work has been done as follows: New valves, seats, springs and guides. Everything has been hot tanked. Finally the question:I haven't rebuilt the starter yet so I crank it to start it. Only takes about three or four cranks to start. As it gets warm it starts to miss. after running for ten minutes it seems to break up pretty bad. Is this a bad carburator or is it something in the mag? Thanks for all your help.

Jeff, I rebuild F/M mags. If the problem is in the mag, here's a couple easy tasks to try. First, make sure the contact set is clean and the gap is correct. (.020) Also, sometimes the condensor may start to fail causing the engine to miss or shut down as it warms up. Make sure the plugs are non-resistor, & plug wires solid core and not suppression type. Also, inspect in the cover or cap (depending on which model mag) for any carbon tracking, which will cause a miss. If everything seems to be okay with the mag, it could be a fuel delivery problem.....

jeff the first thing i would be looking at is your valve lash when cold .010 thousands i think.as the tractor gets warm and valve lash decreases may be holding some valves slightly open hence the miss let us know how it turns out.rudy
