HOT start 180 hp engine

Lycoming says "Priming can best be accomplished with an engine priming
system, as opposed to use of the throttle." Later in the same paragraph,
they say "Lycoming engines of more than 118 hp have an throttle pump which
can be used for priming under moderate ambient (I would underline that word
if I could) temperature conditions while turning the engine with the
starter."

Ambient is outside air, as you know, and the procedure discussed is an
initial start, not a hot engine procedure. I always assume that a hot
engine's fuel lines are still full after the last shutdown, and don't prime
a hot engine at all.

But I don't have the book on your airplane/engine combination...

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.
