Re: stalling issue

6.5psi a little steep for a carb, try backing it down to around 5. What brand carb?

Timing dead on what? Can't set timing to factory spec since swapped to a carb - timing should be somewhere around 10-15*BTDC.

Re: stalling issue

Too much psi for an Edelbrock. Manual states 5.5psi- no more.
