My friend was working on my moped today. He put in a new spark plug and cleaned out the carb, but it still runs for only about a hundred yards before it stops then we have to let it sit for a while before we can run it again. It might possibly be bad gas, so we still have yet to empty the tank and put in fresh gas. One thing we ran into is that on the left side of the moped above the pedal, there's a hole that leaks gas. We have no idea why it's there, and we don't know if it's supposed to be there but is just missing a part or not. My friend thinks that someone might have tried to drill a hole in it for some reason, but accidentally hit the tank. Right now, we just partially put a bolt in the hole to stop the leak (hole looks threaded, but we didn't have a bolt with the right thread size).
Anybody know if there's supposed to be a hole there? Or if the hole was made for some sort of a modification? Sorry, I don't have any pictures. I left the moped at his house.
