Her is one for the "old school" Mechanics out there. 65 Mustang?
I was 15 years old and saved up some money to buy a 1965 Ford Mustang Coupe, the Coupe's with the 200 Six cylinders were a dime a dozen back in 1986. The engine did not need to be overhauled but I did anyway. I was going to tech school for automobile mechanics, and my Dad had offered to pay for all the parts. I did all the head work myself, got all new parts, new paint job for the motor, the works. To make a long story short every little thing was replaced on the engine. Well about two weeks into all my glory of succesfully rebuilding a Ford 200 six cylinder I was on my way home with a great big head of accualy rebuilding something and it working, when all hell broke loose. She was poping through the carb, she was back firing through the tail pipe. It was so imbarising, so I pulled over let the car sit for about 5 minuets. I then turn the key and she begain to run normal. About ten more minuets of driving it all started agian. What was it? Here is a clue the part cost about $1.50
