I have tried running the c6 turbo plug but the motor will not run without the glow warmer on the plug.
any help will be greatly appreciaed
BTW i am running 30 % nitro never had a prob with the fuel
Why the extra .01mm shim? Not needed. The +4 will run jut fine on 30% with the stock shimming. Could be the culprit.
Edit; also try the Odonnell Plugs. They are awesome in the Novas. 97T
