RE: No thank you
Many years ago I had stopped in a nasty rain storm to try to help two
'damsels in distress' with a stalled car.  Another guy had stopped
also.  They had the hood up and were turning the engine over, just
barely, when it backfired and started a stack fire in the carburetor
(the air cleaner was off).  I told them to turn the engine over to
suck the fire back into the intake, but the gal panicked and got out
of the car, refused to try.  I went back to my car, got my
extinguisher, came back just as something let go and the fire started
to spread.  I hit it with the powder and put it out.  And then I
realized that I had just filled the carburetor with powder, all the
way.  I smiled, said I had to go, and left.  Didn't get any thank yous
either....
