Should be a lsight bit of daylight between plastic swivel and blue collet, and there should be slight preload on return spring.
I need to check everything again just to be sure. But wouldnt the throttle get stuck open more often? And why does this only happen on certain days? Like the weekend before last it didnt happen at all. Now this last weekend it happened quite often.
I mean could it be an airleak? I would think that it would happen more often than only when i hit a jump. And its a steady, high rpm that drops to normal once i hit the brakes.
Its really hard to explain for me here on the forums. lol. Ill have to try and maybe get a video next time im at the track if its doing it.
I dont know. Ill have to do more testing once i get my truggy back togather and get back to the track.
