HOW TO CHECK FOR A AIR LEAK?
HEY GUYS, need to know how you all check for a air leak. i have a os .12tr slide carb that intermitantly will run lean on the track, go to a parking lot truck runs great tank after tank, race offroad-flame out. i have changed fuel tank, fuel line from tank to engine. I have sealed the back plate, carb and high side needle. i have noticed alot of oil at the crankshaft bearing.
