Full throttle with carburetor head applied is also likely to cause
detonation due to an excessively lean mixture. This preignition
applies all the instantaneous force of the _exploding_ (as opposed to
burning) gasoline/air mixture directly against the top of an ascending
(not descending as normal) piston. Detonation can bend piston rods or
crack the case. Over a longer period of time, detonation can burn
through the top of aluminum pistons.
