I am working towards repainting the GMC's engine block. Currently it is black. It will be Chevrolet Hugger Orange when I am done. Before stripping down the engine for the paint job, I decided to turn it over. It hasn't been cranked in quite a while. How many years has it been? After charging the battery, I sprayed a little starter fluid in the carb, hooked the ignition wire to the battery and tapped the starter wire on the (+) battery post. The engine turned over and a few cylinders fired off. Sweet! Oh yeah, and flames came shooting out of the exhaust manifold.
