yes top gun it is aac....glue the sleeve in with what? if that would help i guess its worth a try...when my engine broke or (burned a hole) it was pretty lean i developed an air leak somwhere and i was just trying to get another lap in the qualifier......stupid me! biggest mistake i ever made!! what my motor would do (when it was new) is start up fine then stall soon as i apply some throttle...seemed like no matter where i put my settings it would just stall anyway...it would also start (from cold)run for a little while stall then when i try to restart it wouldnt fire?? even after the last run was coming off at 240 deg??? with from what i saw as a great tune...fast punchy everything i wanted...have you heard of anybody haveing the idle screw back out?? i think this happend to me last run ive yet to really look but it seemed as if the slide was completely closed??? its also got a killer pinch is that because of aac?? how long do i have to run this thing before it just plain starts easier!!
