alright, question. i cant seem to figure it out. but when i first start my blaster, and its cold, so it hasent ran in like a day or so, i start it without any choke, since i never need to, and it always starts 1 kick. but the weird thing is, is that it revs really high for about a minute or so, than finally goes to normal idle when the engine is somewhat warm. its like the slide is stuck open, but its not. the only way to stop it is to put the choke on half for like 1 second, and its normal...... i leak tested it, and there were no leaks, so that leaves me to belive that eaither the pilot jet needs i size bigger, or exhaust is leaking. my air screw is about 1 turn out from full in. none of this is hindering preformance or anything. it still hits hard when i hit the power band and everything. so ehat can it be?
