Stop in for a cup of coffee

I do the same way, sometimes the fuel system doesn't prime until you actually have rpm. Hang a tank and a line prime the carb. Spray bottle with gas. If thats a new cam dont keep cranking and cranking though.

I guess I should get a can of starter fluid.

Btw, my heads are casting number 3769974, probably 75-76. Should be ok with unleaded, right?
