I'd opt for
defect advance mechanism or
a faulty capacitor.
Curious....

Subject: Dead 1974 MGB - Quiz

> Your British car quiz for the day. Only a British car could do this !!
> My 1974 MGB died the other day. I was cruising at about 4200 RPM -
running perfect. When I slowed down the car died and would not re-start.
Here's the details.
> Above approx 4000 RPM - Ran perfect, no miss, good power.
> Below approx 3500 RPM - Absolutely no run. Acted like someone turned off
the key.
> Once died would not re-start (either hot or cold). Cranking speed
perfect. No evidence of any cylinders firing while cranking.
> Would start using ether (hot or cold). But no run below approx 3500 RPM.
> I finally found the problem and fixed it. After stewing over it for three
days, I could only come up with two things that could cause this problem.
After fixing the car, I realized that there is really only one thing it
could have been (IMHO).
> Anyone want to take a shot ??? I'll post what fixed it in a few days.
> Kelvin, are you there & brave enough ??

> Summary: In the above scenario, what would allow it to run perfectly
above approx 4000 RPM and not run al all below approx 3500 RPM and be
repeatable ??
