273 spark plug mishap

Just put the correct ones in. It doesnt take much to light off a cylinder. I run a long reach AMC/late Imperial plug on my slant...wrong plug, right performance gain. Its farther reach puts the kernal farther into the combustion chamber. Putting the kernel deep in the hole is a oil foul prevention technique. First thing I always do on a used car purchase is a wash and wax, complete tune up, brake pad change and oil change. Its all on me after that and a great way to get to know your "new" car
