Problems: Electical or Fuel?

PKRWUD · 09-27-2001, 07:04 AM

Ignition System:
I would replace the plug wires because I'm that kind of guy. The best ignition system in the world isn't worth much if the energy can't get to the plugs.
I would try and borrow a coil, and see if there's any difference. If there is, replace it. If not, keep yours.

Fuel System:
Which fuel filter did you replace? Most Holleys have a bronze filter in the bowl where the fuel line fitting attaches. Make sure this is replaced or removed (if you have an inline filter).
Check your line pressure at idle and at 4000 rpm. Make sure it's no lower than 6psi.
Check the float level in your secondary bowl.
Make sure your power valve isn't stuck shut.
Is your carb Vacuum Secondaries or Mechanical Secondaries?
If Vac, which secondary spring are you using?
If Mech, what are your secondary jets?

Take care
