Let it sit overnight then it may run ok after all the fluid is burnt out of the muffler and tailpipe. If you have close neighbors, do it when they are not at home, it will smoke them out. Al
I remember my dad using diesel fuel like that. It smoked like all hell, but would loosen carbon, free gummy or stuck valves, & stuck rings. It seemed to work. It would smoke up the neighborhood so bad that one time the fire department showed up.
