Have an 80 MGB V8 conversion that has developed a problem I can't get my
hands around. When cold it coughs and sputters when first starting up and
when warm will not run at idle without stalling after several minutes.
Thinking it might be an electrical issue, I replaced the plugs, plug wires,
distributor cap, coil, and battery. It has a PerTronix Ignitor module
installed which I did not replace. The battery shows 12.7 volts on my meter.
The alternator is producing 14.6 volts at ~1500 RPMs and 14.3 under load.
Fuel is fed to an Edelbrock 1404 carburetor via a Facet electric pump with
new filters in the line at the pump and just before the carburetor. I use 93
octane non-ethanol gas. I appreciate any thoughts or suggestions you may
