Quote: I'm not 100% sure what you mean when you say spray the intake? I've heard of it, but what are you spraying it with?
Spray it with carb or brake cleaner.. it has to be a flammable product ... but if its leaking it will suck in the carb cleaner and you will hear the revs come up(its burning the cleaner like fuel)
I have had good luck using an unlit propane torch. Crack the valve and wave it around the intake flanges and carb base. If you get near a leak , the rpm's will take off.
That works fine also... like I said .. any product that is flammable will work
