jerdavis,
Always love to hear a story. Yours may be true for mine on a long slow aproach I dont run much rpm so it maybe what you are describing is happening to me. I may start running up some rpms on it on the ground to clear it out some.

Also someone had asked about a rebuild of the carb. I got the engine used with the old magneto and converted it to EI. At that time I rebuilt the carb. I replaced everything I could with the rebuild kit.
Thanks Alan
