Has any of you has ever discovered something during the pre-flight
inspection that necessitated a significant deferrment of your flight
plan or a cancelation altogether? Just curious, that's all.

While a student pilot, Tomahawk fuel selector valve broken/faulty -
leaked fuel onto the inside of the engine cowl.

But... didn't pick it up during pre-flight (valve worked OK in the off
position, which it was "parked" in). Noted it in the cabin, very strong
fuel smell after startup. Shutdown and re-inspected the engine, fuel
was visibly leaking in the ON position (not sure what side/tank was
selected, IIRC the Tomahawk has a left/right/off (no both?)).

Reported it and then carried on in a different Tramahawk.

You're right, there is no "both" position.
