No start issue Im a little frustrated
you say "trying to start finally " so is this a fresh engine build ? If so maybe the distributor is dropped in 1/2 round wrong. Thn if its one that has sat a long time, fuel quality and plugs as mentioned before should be checked.
Folks go to a lot of trouble diagnosing a ballast resistor when really all thats needed is to take it off and look at the back side. Good luck
