Thanks for all of the help guys I will try the foam thing.. I took it to work today because i work at a large auto repair shop in lex.. My boss is as good of a hand at rc aircraft as i know and of course it now doesn't have any bubbles.. ran 2 tanks of fuel through it and it ran perfect the whole time.. Looks like danny will have to fly with me all the time... Have now clue what cahnged other thana the temp it has been about 35 degrees when I have been running it at home and it was about 65 in the shop today.. Danny adjusted the needle also.. I was about a half turn too rich.. I really thank you guys for your help!!!! any other suggestions will be appreciated.. I will find out for sure friday about 12:30 If it is fixed or not it is going up then.... Thanks By the way the air bubbles are comming all the way from the muffler to the tank then a few secs later i see them heading for the needle then i can watch them pass right through to the carb.. Not doing in the line from the needle to the carb now that is set a little leaner Thanks
