I have a super tigre ABC 45, I put a new high speed needle valve housing on and the motor didnt run right. I messed around with the idle mixture screw and now the motor isnt right. it will idle fine but when i open the throttle up to go to full power the motor hesitates and spudders really bad for about 10 seconds and then starts to speed up. In the air it is ok but when I do a touch and go it is hard to pull out with enough speed. Can anyone tell me how to reset the idle mixture. If anyone is in the kalamazoo area, I would love you stopped by and helped, thanks
