The Puzzler

RAY: Well, back in the early days, before they had figured out this phenomenon, when pilots flew under damp and cool conditions, the carburetors would...

TOM: Ice up.

RAY: Ice up. Exactly.

TOM: Oh, and they would make it backfire to blow the ice out.

RAY: To blow the ice out.

TOM: Blow it out your carburetor, as they say.

RAY: So to speak. Blow the ice out, baby! And they would either lean out the mixture or advance the timing or do whatever it took to get the thing to pop back through the carburetor, thus expelling the ice which, if it were allowed to build up, would eventually stall the engine and then seize.

TOM: And that would be not good.

RAY: That would be not good. And, of course, the same thing happens to automobiles. It can happen to automobiles.

TOM: Yeah.

RAY: And cars have some crude little device which prevents this, and, of course, airplane engines don't really have carburetors anymore. But that's why they did it.

TOM: Whew!

RAY: So who's our winner this week?

TOM: The winner is Ginger Culbertson from Greenville, South Carolina.
