[Big hammer]

When I’ve had a hot no start, I’ve pulled the choke and crank it 2-3 turns and it starts. I think that if it’s a vapor lock, pulling the choke and cranking pulls the vapor out unblocking the vapor lock. Coolant temperature 195*F , that problem has been resolved. Using the tools you have with the model A , adjusting timing, adjusting GAV, watching the ammeter wiggle, pulling the choke can help yourself with starting issues.
