years ago i had a beetle go up in flames. it was a horrible experience.
the previous night was spent reintsalling a newly breathed on engine. bigger capacity, big webber carb, bigger valves, ported and polished. went like stink.
as we were messing about with lead lamps and fuel lines i took the fire extinguisher out of the car and took it to the engine bay. next day up and on to test out the new mods, totally forgetting to put the extinguisher back in the car.
i am sure you can guess the rest
