There's kind of a running joke/contest of who has the farthest squirt out the spark plug holes when the engine breaks loose. I think member Steve'o may hold the record.
Many years ago, when I was young and stupid, unlike now that I am old and stupid, I was trying to start an old Benly, with no success. Poured some fuel down the plug hole and had the plug alongside when I kicked it over. Stream of petrol came gushing out, plug fired and ignited it and shot this stream of flame that just happened to go straight into the petrol can which still had its lid off. In a garage, no less. Ran like hell and waited for the inevitable, but nothing much happened apart from a fire in the petrol can. Ran over, screwed the lid on it and it eventually snuffed out; large calibre bullet dodged. If you were into special effects stunts you probably couldn't have arranged that.
