aint exactly a trx90 or a quad but this is the best place i could think to ask this..I put my buddies 88cc big bore kit in his 50 today and got it runnin good, it idles fine but when I twist the throttle it'll die, if I feather the throttle it'll rev up fine and if the rpms are above idle it go fine but I can't figure out why it'll die when I hit the throttle at idle? I've cleaned the carb, messed with all the adjustments on the carb. anybody think it could be the timing is still off a tooth?? or any ideas on how to fix it?
