A little over a year ago I bought a 66 Fury III in great shape. This is the first car I have ever wrenched on, so the learning curve is quite big. Through the internet, some mopar guys at local shops and really helpful guys in my unit I have learned alot about my car over the year. In October the car started to stall while driving regardless of speed, shift to neutral and she'd fire right back up. Gave her a tune-up near the end of Oct and then had major ankle reconstruction surgery which put me out till Thanksgiving. She sounded like death warmed over right after the tune-up (cap, rotor, plugs, wires, fuel filter, battery cables, etc.) Rebuilt the carb (original 2bbl Carter) last spring and she ran great till then. I have a 2bbl Holley and I am getting an adapter milled to mate the poly to the carb locally and he's gonna show me how to tune it and re-jet if necessary. Only problem is, after all the wire replacement, batteries, alternators and everything else it stalls when i shift out of neutral or park. If anyone can help that would be great thanks

 

some super weird occurrence with a bad neutral safety switch?

 

It sounds like it may be a timing issue. Are you sure that your plug wires are in the corresponding holes in the distributor cap? It can run if they are all one hole off, if the timing is adjusted to the max. That is where I would start. Make sure that #1 plug wire is in the corresponding #1 distributor hole.

 

Or another guess would be idle speed to slow

 

mine did the same before i replaced the carb...hard starts too?

 

Hey Fury,my friend had the same problem and he changed everyting ,Every time he put it in gear it stalled .Ended up to be a bad distributor.

 

It sounds like it may well be a timing issue or you may have some misfiring going on. If you haven't already, change the points and condenser.
