You probably have after-ignition, usually caused by operating with dirty fuel. The way a mechanic explained it to me is that there is (very small) debris in the cylinder, on the piston. When you hav edriven enough that the engine gets to a good tempertature and turn the engine off, the debris (if it's large enough) is red hot and causes any small amount of fuel to ignite, thus causing the piston to go down, thus causing more gas to come in to the next piston ready to fire, debris is hot, and it just goes on and on. Seek the advice of a knowledgeable mechanic or get Chilton's mechanic repair book and check the trouble-shooting section. In short, my opinion? bad gas, my friend. Change gas stations.
