Dynamite .26

[bazooka_cow]

ok so i have a savage .21 that came with a dynamite .26 motor. i took the 21 out and put the 26 in the other day. i cant ever seem to get the dynamite tuned it right it always gets so close to being perfect then i'll run it it runs great for a couple passes and then i punch it full throttle and it sputters i adjust my needles and it does the same thing. i was just wondering if everyone has had this problem before or is running a dynamite 26? i was wondering if the problem could be the idle screw being in to far the idle doesn't sound to high but if i'm running a little rich and the screw is in to far it could cause that. i already did the engine seal mod so it shouldn't be an extra air problem. any thoughts? or imputs on the dyna .26? tips maybe? anything? haha

:tired:

nah fuel lines are good a just replace them i got in tuned it pretty good now it took 3 tanks of fuel but it sounds good and is blowing the right amount of smoke i think i dunno i need to take it to a bigger place to run it i guess to really see. thanks though
