Hey guys. I just bought a 1985 Big Red. It ran perfect for about an hour or so and then died. I quickly found it was not getting gas to the carb. I changed the filter, hopped back on it only to find it quitting again in a couple of minutes. Petcock is working fine. Took the gas cap off and heard a rush air enter the tank. Checked the vent and it was in the "on" position. Is there a simple fix for these or is the cap junk? For now, it's sitting loose on the tank, allowing enough air inside to keep it running. I need a fix before TF'06. Running a loose cap at Haspin won't work!!! I don't see any way to take it apart. Any replies will be appreciated. Thanks wheelerheads. ATC4everBob
