Alan, I have great respect for your knowledge of british cars and Healeys 
and I sincerely mean that, but in this case I rather doubt there is a fuel 
delivery problem, description of the issue is the car runs and accelerates 
fine until you stick it in overdrive, my experience with fuel blockage from 
sediment is that it cuts off the fuel over a time running, particularly if 
running higher engine speeds, higher volumes of fuel causes the sediment to 
rush to a restrictive point and then you don't have enough gas.

Kicking it into overdrive would not cause this problem immediately, it would 
more likely manifest itself at sustained high speeds in direct top than if 
shifting into O/D.

My money is on (can't remember John Harper?) whoever stated a high solenoid 
draw or other issue with current draw when shifting into overdrive, causing 
an immediate weak spark and the symptoms described. I would put the car on 
jackstands, take the tunnel off and either test current draw on the solenoid 
when in operation, or test by manually pulling the accuating lever and see 
if it bogs when the electricals are not involved.
