Seems like my Allis chalmers Model G is giving me a little problem,can not adjust the carbuerator to get any power out of it,was told the valves were to tight,can anyone tell me what the adjustment should be on the valves.
 
Valve setting for intake and exhaust is .10 hot. If the tractor has a significant loss of power, you could have a stuck valve. That is common in flat head engines. You can remove the spark plugs and see half of the valves. You can watch to see if they open and close when the engine is turned over.
