I'm already planning on a complete tune-up for the spring: new distributor cap, rotor, wires, plugs -- I already have the electronic ignition. I have a brand-new carburetor as of last spring. So this question is more general interest than a pressing need, at the moment.
Basically, my engine behaves like this: starts right up and runs smoothly. However, if I throttle down quickly the engine will go right down to almost stalling, then "catch" again and come up to where the idle is set. Sometimes it does stall out, but starts right back up again. If I slowly throttle down it will settle into its idle quite nicely.
Is this the sort of behavior that changing the above parts will cure? Or is it indicative of something else, maybe the weights in the distributor (which looked fine the last time I looked at them in the summer)?
I'm also not quite sure about the idle mixture setting, as the screw is difficult to get to, but I have at least tried to set it as best as I can. Could it be that I need the adjustable main jet add-on for the carb, or should the brand-new carb be OK as it is?
I'm interested in seeing everyone's opinion, and thanks!
