Status: offline 		I have for the most part broken in the new motor on my 1/8 Scale buggy .. Its a sportwerks turmoil .21 v2 and runs great... My questions are the following:

After it sits at idle for a few seconds and I jump the throttle its seems to choke a little then clears out (what causes this)
Also when I am running at 3/4 throttle then jump the throttle it runs for like to seconds then kinda pops the front end dips a little (like I am putting the breaks on then gets going again.

Thanks as always

Status: offline 		It may be a little rich on top. The Idle thing is as the car sits idling, fuel builds up. We call it loading up. Many people (me included) tune there motor a little on the rich side and this loading up at ildle is common. The 3/4 throttle thing you mention is hard to say without hearing it happen but if you are seeing a good amount of smoke when you run. You could lean it a little on top & see if that helps. Be sure it always smokes though.
