I have a 1973 TVR 2500M. Last winter I installed a rebuilt Halkias engine and brand new SU carbs. Car had been running very well during break in period and then I had my car guy here lean out the carbs. Now I'm getting some intermittent back fire at highway speeds and when the car slows down my RPMs drop to the point where the car nearly stalls and then catches it's breath before spooning back up. RPMs seem to be hunting.
Any thoughts and ideas?
