My exhaust broke off and I kept dtiving it and I felt more power.
I change the exhaust with another dynamite exhaust system and the engine will not run rite. I was running wildcat 20% and I just change to blue thunder 20%, before all of this trouble my high needle was a little under 2 turns and the low needle was around three turns out. Now I am playing with the high needle from 1 1/2 turn all the way to 2 1/4 turn and the low needle from 1 3/4 all the way to 3 turns and the problem is still there. The problem is the car starts fine every time and when I rev it to keep it running is shut off. when I do get running a little better and I put it on the ground and press the trigger it acts like its very rich and it dont move, it just idle like if I was not pressing the trigger. Then a next minute I will act like its very lean and take off and bog down, sometime when its far away and I press the trigger and it dont move I think it cut out but it didn't . I brought it close to me and press the trigger and I see the carb arm open but it just dont move. I have new glow plug#8, new fuel tank and tubing. Thanks.
