Need help please! Run rich / Lean adjustment screw coming lose!
 

Hi. My Hobao Hyper SS Cage Nitro has a bit of a problem and I thought someone may be able to help me please?
The screw that adjusts the tuning on the engine loosens itself up when the car goes off - does anyone know what I can do so that the screw keeps in position?
Any help appreciated - I'm a total noob!
Regards
Andy

you could put just a little plumber's tape around the threads but it probably needs a new oring on the screw too

Problem
 

Degrease the o ring on the screw body. If that fails then if you know the ball park setting put some thread lock on the threads. Not ideal.
