But I also wouldn't rule out an ignition problem like a bad condensor or points closing up or -heaven forbid- you have the plug wires on wrong (using a 302 firing order for a 351).
With the engine off, take off the air cleaner and look down the venturi. Open the throttle wide open. You should see a shot of fuel going into each venturi. This is your accelerator pump circuit. If you don't see the pump shot you know there is a problem with the accelerator pump. If you do see the shot, that doesn't mean you don't have other carb issues, just that the most obvious one isn't it.
It could still be, and what I think is, a vacuum leak. Check that all the hoses are connected to where they are supposed to be from end-to-end, that the carb base is tight. You should also go around the carb and intake gasket areas with a can of WD-40. You spray around to see if this gives you a more stable idle. Another shortcut trick to check for vacuum leaks is to close up the choke plate to see if the idle stabilizes. What this does is bring the air/fuel ratio back into balance and stabilizes the idle. It's best to do this with a vacuum gauge since you'll be able to see fluctuations on the gauge.
Hope some of this helps. |
