Hello. I was up at college for two months and I came home to find my moped wouldn't start. I checked the plug and it wasnt getting any fuel obviously. The tank was full. I then put gas directly into the cylinder and it started right up. I had to do this a few times until it got warm. I then rode it for an hour with no problems. The next day the same thing happened and I had to start it the same way. I was wondering if there is indeed a problem in the fuel system somewhere where the engine can't get fuel, or is it just the cold (i live in wisconsin) or the old gas is making it hard to start. Thanks for any suggestions.
