Anyone? 20%? 25%? 30%?

Any help on what % Nitro to run and information on shims that are installed in the engine from the factory or come seperately included would be greatly appreciated.

I have been running the Novarossi 3-port (on 30%), but I am going to give the GO engine a try.

Thanks.

BTW... a little while back I was looking for a rotor start for the GO engines and found this --> http://www.go-engine.com/go_engine-2.htm
