i have a 92 indy 500, and i rebuilt the track, before i pulled it into the shop, it ran fine. but now from sitting for a week or 2, it starts and runs up to 2200 and stays there, its like its govered.. its spittin fuel into the airbox., changed the CDI/coil, gettin nice blue spark. and while its running. and i unplug one (dont matter which one) plug. it dosnt change the way the engine runs. obviously if i unplug both it dies. ... carbs have been cleaned, has 230 jets in it. i have tried adjusting the choke, the air ajustment screw is backed out 1 full turn, like the manual says.... any ideas!?!?!?!
