ive just broken in 3 novarossi engines for my 3 drivers for the worlds, 2 Plus 12-3CT Tuned's and a LLT3 Tuned and you dont need to pre-heat the engine, just push hard down on the starter box and dont back off so it turns over the engine and then put the ignighter on and let it idle for a tank, then drive it around the track rich as making it reach temps of 100*C and 110, towards the end of the 1 litre and man these engines are fast and we havent even tuned it for racing or put the runnertime race fuel that were gona use at the worlds,
