Well, I'm not totally sure it is a carb problem. The motor is just not dependable. It runs great, has plenty of power, but it just dies once in awhile in flight for what seems like random reasons. The last time in a hover at 30 ft. and killed my airplane. Some days it runs, some days it doesn't.
I have the snorkel on it, as well as baffeling. One guy told me it could be the carb is getting too hot because the muffler is about a 1/4 inch from it. Any suggestions????
