I installed a 10 second time delay relay on the cooling fans (no extra wiring required just replace the existing cooling fan relay) and on the headlights!
it really makes a big difference in the hot crank rpm!!
I also installed an electric fuel pump with a built-in one way valve (fuel is getting fed around the mechanical fuel pump) to give it a short prime before cranking… just a momentary pushbutton switch would do the trick!
and I put a heat protection sleeve over the fuel line…
And I did the 1/2” insulation spacer on the carburetor…
not sure which is the reason but the engine starts always within 2 seconds… no matter how hot….
