Hi

I have a Rush evo and I am having a few problems with the engine.
1. Every time I take my car for a run it always over heats. I have done every thing to stop itfrom over heating but still it does not stop.
2. The spur gear on my Rush evo keeps striping dot any suggestions?

1. make the fuel mix richer

2. set the mesh right, you will probably nedd some new engine mounts to adjust the CB and spur right, and wilth engine mounts you can change the number of teeth on th cb.... hpi has some aluminum engine mounts for like 3$

Since you said that ou keep over heating and the spur keeps stripping let me ask you this is it after you have been driving for at least 2-3min? And is the response of the engine really slow? You may have A air leak around the high speed. Check everything is tight then go into detail with your problem on here the more info you give us the better we are to help you.

Also try A cooler plug something like A a8 it makes A big difference sometimes and won't bust your wallet you probably have A a3 in there now.
