Group,

        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 ??
