Background: '72 MGB with later 70's engine, starts and runs fine cold, but once warmed up stalls out and may or may not start again, only to repeat the problem. I thought it was a shelled distributor (see previous thread), and after getting it rebuilt by Jeff at Advanced, reinstalled it this morning and it fired right up. Set the timing as Jeff indicated, things looked and sounded good, so I took it out around the neighborhood for a spin. Once I got it warmed up (maybe 10 minutes of driving) and as I was driving down a long hill it started to fade as if it was getting no gas. Rolled to a stop, tried to start it again (which it did but not for long), and acted like it was starved for gas. Wound up towing it home - again.
I have eliminated the dizzy as the problem, so all I can think of is carburetor or coil. I've heard of coils going bad once they heat up, but don't know the symptoms. This car has a Weber 38/38 side draft with electric choke. I bought the car last summer with that setup, and know nothing about Weber carbs. Could this be a needle valve or float issue? There is plenty of gas to the carb, as I've tested the fuel flow, but not the fuel pressure. I have a see-though filter that sits next to the carb, and it is always full.
Any ideas? I'd sure like to drive this thing before the snow starts to fall and I have to wait another six months.
