Hard Starting After Warmed Up.....Arrrg

Believe me you aint alone on the timing thing. Its the terminology thats the ***** of it. I just fingered it out myself. Lots of capable people in this thread will help. Im not going to confuse the issue. BUT could the diaphragm in the dizzy be bitched?? Maybe put a vacuum pump on the dizzy to see if it holds vacuum??

FYI, I run a Eddy 1406 on a 67 273 4 bbl. We had initial fuel percolating problems, put a thin spacer and it fixed it.
I know gas is junk now a days, but Im not sure that is the problem. I run 87 octane in it and NEVER have a start issue.
Clean elec connections, maybe try a new fuel filter too??
