A few years ago a former student called me up to ask for some advice on getting an engine started, one he had just rebuilt and reinstalled in a friend's car. The engine had been out of the car for a little over two months, as he was doing the rebuild as side work to his day job in a dealer shop. After several phone conversations with no luck, I met him at the job site and participated in the startup effort- - - - -with no success whatsoever! Gas, spark, valve and ignition timing, compression, etc. all checked out OK. Still, we've got a "crank- - - -no start" situation. Double check everything- - - -and again- - - -and again! "Hmmmmm- - - - -the gas smells a little funky" Pour a little out on the ground- - - -toss a march- - - -it puts the cotton-pickin' match out! In about two months, the gasoline had gotten stale enough it would not burn! We rigged a gravity flow fuel supply to the carburetor and the engine fired up on the first try!
