My 1973 Skyhawk has the 360/180 hp engine carburated.
When the engine is hot it is difficult to start.
My procedure is master switch battery side on, fuel pump on. Prime
throttle 3
times. Fuel pump off, turn starter while advancing the throttle.
Today she would not fire and the battery went south.

Any recommendations, suggestions.
Will check timing and Magnetos tomorrow.

On my O-360, when hot, I don't prime at all. Pump throttle once, crack
1/4"
and crank. Starts every time.

This on a Husky - no fuel pump.

Same here on my 360/180 powered Maule. In warm weather, cold starts are
easy with 3 pumps of throttle, when engine is already hot, 1 pump does it.
No primer except with temp is 55F or less. Never use the fuel pump.
