I know about cars. Enough to do a valve job or change a crankshaft.

Lawnmower carburetors look to me like fine watches. Small precise
springs. Multiple bell cranks. Lots of little things that have to
work together as a fine orchestra.

I thought I knew enough to fix my own. It's just a carb, right?

Saw a cartoon in a medical magazine. Car mechanic looking at the part in his
hand as he says to the owner: "There's a lot about carburetors that science
still doesn't completely understand."
