So I rebuilt the carb on the B, got it started and it sounded and ran really well for about 15 min. Then all the sudden she sounded like a hit and miss engine with one cylinder actually hitting a fire stroke and the other cylinder popping white smoke out the air pipe. (I have the air cleaner and air stack off for cleaning, it was plugged up)
I am guessing one of the intake valves is not closing like it should allowing the bypass back through the carb and air stack. I also noticed once she died that the intake just past the carb was a frosted up a bit. It was mid 30s and had tried to snow so the air cold and wet.
Any ideas? I don't want to pull the head to check the valves, but if I have to I will. I did pull the carb back off and will check it out and change the plugs.
This is a new to me tractor, and my first antique one so excuse all the questions.
