I just purchased a 74' MGB and I am only able to start the car once. The car will not idle - I have to keep my foot on the gas to keep it running. If I let go of the gas and let it stall out I am unable to get it started again until the next day - I know this must be due to flooding the engine. Any help would be great. I am new to these cars and am just getting into working on the motor. Thanks
