Hi I have a 88 par car that won't start. i could get it to run by squirting fuel in the carb. I took the carb apart and found the main jet blocked. Put it back to gether and it would run for 30 sec. Now it won't start at all. even with gas in the carb. looks like no spark. Checked the coil I think it is bad. Primary is open ? Could I buy a car coil, would that work and what car coil would work?
