I rebuilt this Rochester B carb last year and I start my truck about once a month. Actually I should say Engine/Chassis as the body is removed for restoration. So anyway I crank it up and let it run for twenty minutes or so just to keep the condenstaion out and the top end oiled up. But today the carb started leaking from the pump assy arm that sticks through the housing bottom and connects to the throttle linkage. So here's the question or problem. Is it leaking from lack of usage or is the accelerator pump probably just bad and by passing. I wondered if there was anything to this ethanol issue and if I need a special accelerator pump to put in the carb. Anyone know ofa source for a kit that has ethanol proof stuff? Any help appreciated.
