Hot start problems

[Psycho71]

On a cold start, i jab the throttle once to set the choke, then it fires within a full revolution. Once warm, I never have to touch the throttle to start it, it'll fire right up.

Could it be that you, or your wife, don't need to touch the throttle before a warm start attempt? Just throwing it out there. Every carbed vehicle i've ever had, had it's own little quirk when starting. Even my boat does. Once figured out it fires right up too.

I know I don't hit the throttle on hot start. And she swears she isn't either.  The problem as she describes it is it does start for a few seconds, long enough to put on her seatbelt then dies and won't restart without choke intervention. It will also give a little smoke if you rev the engine pretty good while parked. So I think I may have a combo of heatsoak and too rich. She's an old truck with plenty of problems but she goes good when she goes

Check the choke operation, check for leaking well plugs, check the pick up coil.

vile whats a well plug?

[timthescarrd]

If I'm not wrong, well plugs are the notorious little plugs on the bottom of quadrajets known to begin leaking and dropping extra fuel into the intake.  common fix is to epoxy 'em during a rebuild, best fix is to drill and tap them and then twist in a plug.  Not sure what the pick up coil is though?

[Irish_Alley]

didnt know that was the name for them. but the pick-up coil is under the rotor in the distributor you have to remove the distributor then remove the pin in the gear then slide the shaft out this will expose the pickup coil at the base of the distributor

     Several company's offer carb spacers, do a internet search, then pick which one suits your needs and the needs of your state laws.

why a spacer?
