Some British engines used an oil passage through the carb venturi, a far more

Fuel injection will help a lot, but mounting the carb on top makes
almost no difference.

The Gipsy Major took its carb heat from up next to the
crankcase. As with using undercowl air, the time between startup and
useable heated air is too long and carb ice can form while warming up.
We see carb ice shortly after startup rather regularly here, and
we live in fairly dry country. Need to pull carb heat soon after
startup some mornings. It's a good thing the exhaust piping heats up
quickly.
