its always a little dangerous to argue with the people whoa ctually manufacture the engine... it is possible that cenracing might just be familiar with this engine, and therefore know what they are talking about...

the 2 extra pulls u mention, would be ok so long as everything else is absolutely spot on, a warm engine would help. if someone is having problems it is best to stay on the side of caution cossie, think before u post mate, it will save u looking silly.
