Re: Vapor lock cure for carbed engines

I actually use water to take ethanol out if my fuel it soaks all the Ethonal up and leaves you with pure gas. Add octan booster to get it back up to snuff and you get your ten percent power back.

Also running a return line style fuel pump kills all vapor lock issues. If you still getting vaor lock your fuel is either perculating in the bowls or your intak is way to damn hot and your carb os over atomizing the fuel along with to much heat. As well as if your exhaust is making your fuel lines to hot then that's an issue as well.
A carb spacer will help cool the carb and making restrictors for the exhaust crossover with coke can run helps. As will fuel line insulation and better routing and a cool can as a last resort
