On my grandpa's 1941 B..from having no spark (magneto problems) ....to having crazy high RPM's...(thank you Clooney, it was the head of cotter pin on throttle linkage hitting the carb body). We now have a problem of it running/idleing really rough. If we let it sit and idle a little while, it will straighten out and run really nice, and then go back to running poorly again. We are GUESSING that we are flooding out the engine with gas. Either the jet adjustments are off OR the float is too high???? We have a schable (spelling is bad I'm sure) DLTX 38 (looked like, quit dirty on lettering). There are 2 large L handles for adjusting the jets on top of carb. One says idle jet and the other says load jet. There are some small, brass slot headed screws near the L shaped jets. When we had the carb gone through, the mechanic said to adjust the L shaped handles 2 full turns out. We've played with idle jet (I'm assuming it's the L shaped adjuster) turning it 1 full turn out, 1 1/2 full turn out and 1 3/4 turn out, none seemed to do much good. It seems to backfire sometimes, we tried reversing the magneto wires, but it backfired just turning it over by hand, so we put wires back the way they were. Where do we go from here??? Thanks for all the help. If we had tom pay a dealer to do all this work, I know we couldn't afford to do the job of getting it running, then it would be just another rusty hulk in another fence line. Thanks for all the help!!!!! !!! I've got to go and try to plant some soybeans, we've been so wet we haven't been in the field for almost a month. S MN.
