Need some advice. I can't get the motor in my '63 falcon to idle ... at all! Have tried two different carbs (holley 600 & edelbrock 600) and both exhibit the same problem. Car starts with choke closed on fast idle and runs seemingly fine. When I kick it down after a bit the motor will not hold an idle and will die. It only keeps running if i pump the throttle which to me indicates that it is running off the accelerator pump "squirts".... otherwise it dies out after a few seconds. Both carbs have been rebuild, floats set according to the guidelines and mixture set per initial instructions. Any suggestions on where to go next???

Check for vacuum leaks. Timing

Double Check! Spray some carb cleaner around the base of your spacers to check for leaks and plug up any ports you're not using.

Crap carbs or Vacuum leak.

Did you try to adjust the idle speed screw?

Points! adjust your points! i think i had the same goofy problem with my 63. i thought it was timing and carb but turned out the points needed to be adjusted properly. give it a shot and let us know!

good luck

Leo is onto something. Hundreds of folks bring me their car's cause they're running schitty, and after checking most out it turns out to be weak or badly adjusted points in the cases where the carbs were unmolested.

Thanks for all the ideas. Right now I'm running down the vacuum leak suggestion and will let you know how it comes out. I'm running a Petronix ignition so I don't think the points thing is the problem.

It can be if you are not bypassing the pink ignition resistor wire. Easy to verify - clip a jumper wire direct from the battery or starter relay battery post to the PerTronix RED wire. If it runs better, re-do the wiring to bypass the PINK resistor wire under the dash. PerTronix do not like low the lower voltage from resistors. That said - it's still most likely a vacuum or possibly timing issue.

EDIT: To be clear - only the PerTronix module (assuming a PerTronix-I) will get full BAT voltage - the coil still needs the resistor. The other P-II and P-III versions use no resistor anywhere.

You may also want to check your fuel lines to make sure that none of them are kinked or restricted.

I've had both the Pertronix II and III and there is no resister. Two wire (red/black) hook-up from the module inside the distributor to the +/- on the coil - done.

Correct - if you bypass the factory ignition coil resistor under the dash. The PINK wire.
