Greetings,
I am having a problem with my 1977 MGB retrofitted with Dual SU HIF-4's.
About a month ago, I gave my car a good tune up: new NGK plugs, wires, cap
and rotor, the carburetors where running a little rich, so I leaned them out
just a little bit. The car runs beautifully, 23+ MPG, but with the coming of
hot weather the car has started to run on very badly. I am running 87 octane
right now (due to price) but the gas here in Bakersfield, CA is of fairly
good quality, and the car has not been overheating.
When I turn off the key, the ignition light glows very faintly (as opposed to
glowing very brightly as it did before) and the car continues to run...I
don't mean dieseling, I mean a slight miss, as if I could still drive it
around the block. If I rev the engine, the car misses but revs easily
(sometimes the engine will stall while I am revving, and then the engine will
diesel very badly) ...I have to let the clutch out with the tranny in gear in
order to stop the engine, and only then does the ignition light glow
brightly.
Please help me! I don't know what to do, and I can't have my car in the shop
this week.
Thank you for all suggestions,
Steven Sanchez
