I have a GP dazzler that i put a tt pro 46 on. I have about 15 flights on it now. Since new it has leaned out in the air. I set it with a tach on the ground 400 shy of peak and take it up for a 6-7 min flight and all is well. But when i land it and refuel the plane it will not restart. So i take out the glow plug (os #8) and it will not glow. I have used 3 glow plugs in 15 flights. I am using a 10-6 prop and wildcat 10% nitro 18% oil. I think that the fuel might be foaming causing it to lean out in the air. There are small bubbles in the carb line while running it on the ground. I have put some looser foam around the tank and changed all the tank plumbing. Should i put a sintered clunk on it. It says that sintered clunks should not be used as a fill line?? I dont want to run a 3rd line. The os a3 that i tryed when i ran out of #8's did not burn out after several flights.

Any suggestions?
