Thanks for the suggestions. I should also have mentioned that the carb was professionally rebuilt a few years ago before I bought the car so it looks like new. I do know that it still has the original steel needle though as I believe the needle that came with the kit did not seal well. The car has been running great for the past year until it stalled for the first time a week ago. I just received a replacement needle which I’ll try tomorrow and will double-check the float adjustments also.
