Rapid pumping does indicate empty float bowls. If you have the Hall-effect pump, rather than the transistor assisted points type, I don't trust them. My V8 has one and started doing what you describe

I don't know which one I have. All I know is, removing the pump is such a pain, and me and gasoline don't get a long, so I got a pump that hopefully wouldn't need much maintenance. A couple of people

Thanks for the excellent description, this is the exact problem I had with my A before I pulled her off the road to work on her. My car is a street car and heading into summer here where we'll regul

About 6 years ago, I bought a solid state SU fuel pump from The Roadster Factory. It is still working fine with 70-80,000 miles on it. About 6 months ago, the pump in my other B went south, so I orde

What does an A have for a carb heat shield? I wonder if you could back the thin metal shield with some of that foil-faced underhood insulation or header wrap material, to try to keep the exhaust heat

It has a piece of sheet metal between the carbs and the exhaust manifold. At the ends of this piece there are two bits of asbestos on the side towards the exhaust manifold runners for ports #1 and #4

After a week of hibernation (part rain, part bad dealings with a painter for my house), I took the MG out to drive to work this morning. To start with, I have converted the car to HIFs, and couple of

Generally speaking, one can stop using the choke of the HIFs within 1/4 mile of driving in air temp of 55 degrees. I don't think the stumbling is related to the choke, though it could be a lean mixt
