Inliners International Forums General Discussion Engines Do I really need to heat the intake?

Those core plugs will always leak, maybe not right away, but eventually. So you are at eventually! Do you need to heat the intake, even in warm weather? The short answer is yes, the bottom of the intake needs heat to properly atomize the fuel. It will run, you might not even notice a big difference but it's there. Usually runs rich, maybe a little stumble. I know you don't want to pull the intake, buts it's the proper repair. Have some plugs welded over the steel core plugs. At the same time, if you are using a plate with a gasket for the bottom, have the plate welded to the intake and no chance of leaking from then on.
