You'll find a leak somewhere.

Thank you for replying. I have checked the lines around the fuel pump and up to the carb. I still need to check the lines from the tank and look into the exhaust pipes, which have backfired frequently in the past month. I'll post back if I find anything
Thanks again,
Mark
