I recently did my yearly exchange of bowls due to ethanol. I was happy as a clam and then I noticed this. Right at the bottom of the throttle body shaft there is a leak that starts. I believe it's after the engine shuts off. At first I thought it might be the rear seal on the bottom carb to the body , so i removed the bottom carb. I cleaned the mating surface and put it back and the leak is still there. That seal is new by the way. Is there a seal that comes down through the bodies, on the shaft, that is gone and just letting the gas seep down? It's the right side of the engine and none of those carbs appear to be letting too much gas come into the throat area. Which means the needles are doing their jobs correctly. Anyone??? :facepalm:
