Dearest List,
What coil do you recommend for a stock 67.5 1600?
Thanks,
Robert

Paul,
Change the coil and resistor and see what happens. I do believe a fellow MGB
club member had a similar problem and it turned out to be his coil. Coils
build up heat which is why they have oil to cool them down and also to
insulate them. Ballast resistors also heat up, naturally.
It's a hard call but seems to be the easiest thing to do. The oil could have
leaked from the coil a little at a time through a small crack. A cracked
coil also can make your car hard to start in humid/wet conditions. A friend
had that problem until we changed out the coil after a lot of head
scratching and changing almost everything in the ignition system.
Since you ran about 2 gallons through the fuel pump it shouldn't be that as
fuel pumps can get hot and fail too or if there was something being sucked
into your fuel pickup in the tank.
Good luck
Mike
