old john deere 2BV blower cannot be restarted though it sounds like it would if it got fuel and/or spark. It was running, and, then I mixed new fuel with 2 cycle oil but probably mixed a very excessive oil / fuel mix ratio by mistake, so it was blowing out alot of blue smoke and running rough when I stopped it, but then could not restart the engine. Not sure whether this oil mixture issue is related to the restart problem. Replaced spark plug which was fouled, but cannot restart. Any suggestions on how to restart this engine or what is wrong with it?
