After reviewing the threads that have been coming in tonight there are a number of reasons your car could be misfireing, chocking up and not running.
I always look at the tune up procedures first. Making a list ot things to go over helps to solve problems without losing sight on what you have already done.
Your extensive fuel usage is a simtem of a larger problem. If your using it at that rate and the tune up procedures didn't change any thing, then I would remove the air filter, pull the carb and check the needle valve to see why it's not shutting off. The Coupe supplement shop manual shows the later carb. On the electrical side, I would check the points breaker plate to see if it has movement from side to side, this will keep your points from manitaining the proper point gap.
Also in trouble shooting the carb look for vacuume leaks by spraying WD40 around the openings, if things get better while the engine is running, Keep looking.
