Has anyone found the solution to this common problem for the 2002 prox fan? At cold temperatures (below zero) the sled runs great, it can outrun many 500s, but when it gets up to above 10, the sled loads up when you stop and you have to get off and then give it some throttle until it gets going then jump on. I melted the exhaust side piston two years ago and so we put in both pistons new (which is a pain to get those race pistons). We set the jets to what it comes from the factory. Would it help to run 110+ gas in it? right now we're just using pump gas. and how much would it cost approx to convert it to a 600 liquid?
