Bee1971, I read the threads and complaints before I bought the carb but I wanted to give it as shot. The only reason I decided to do this level of work and documentation was my discovery that my stumble problem was due to a rich condition and not lean.

Nearly all of the 1411 stumble threads tell the reader to make the carb richer automatically and to drill, enlarge and/or bend the pump rod. If I had taken that advise I would have made things worse. I am hoping that the next person who has a stumble problem will see these threads and consider other possibilities before getting out the drill.

There are thousands of 1411's out there and my bet is many of them could be tuned to work. I have gotten 99% of the bugs out of mine and am now just down to the fine-tuning.
