Re: atomic 4 mini explosion
Look at the donut-shaped air filter on any older car. There's always a metal screen or grid around the perimeter and that is no coincidence, that is called a BACKFIRE ARRESTOR because engine with carbs can backfire and spew out flames. On a car that is nasty but you can always walk away. On a boat, that can be lethal if you have to jump overboard.
I knew an old Chevy that was running rough. Took off the air filter to look at the carb and found the float had malfunctioned, the entire top of the carb was filled with gasoline, which was overflowing either into the carb or out on the engine. And if it had run onto the exhaust manifold, it would have made a nasty fire.
These things happen.
If the boat is such a nasty old POS, don't even ask what might be wrong. Don't attempt to run the engine until a mechanic has gone over it, because an A4 is a good simple solid engine, but with enough owner neglect? It could be waiting to turn that boat into a bbq pit.
If you MUST play with it, make Real Damned Sure someone is standing by with an extinguisher, with the pin already pulled and ready to use. The girl(s) will not be happy in a burn ward.
