I have a lot of problems in the mornings trying to warm up my slant, I have to keep pressing the accelerator pedal until it reachs a normal operating temp; if I let go the pedal, the engine stalls... the carb is a Holley 1945 and needs a lot of attention... recently I clenaed it and replaced all the gasket in there. But I noticed that the choke pulloff coil (think it's the right term in English) has been disconnected for as far as I remember. There is the cable from the choke coil with its female plastic covered connector loose. The thing is that there is no other cable to plug it in... it is missing...

How important that cable is, and where can I connect it?

Thanks,

Ed.

The missing part is the choke heater controller. Its job is to modulate electrical power to the heater in the choke thermostat coil. If there is no power to the heater, then the choke coil will stay too cold for too long, and there will be too much choke action. The choke heater controller looks like this:

Image and is NAPA Echlin number 2-1695. So that's one part that needs replacing.

It also sounds like the choke thermostat itself isn't working correctly, if you get stalling when the engine is cold. Is there spring tension in the push-rod that runs up from the choke thermostat to the carburetor, when the engine is cold? If not, there won't be any choke action, the engine will stall (lean) and you need a new choke thermostat, NAPA Echlin 2-326, which looks like this:

The third component of your choke system is the choke pull-off. This is the vacuum-operated pod located on the driver's side of the carburetor. When vacuum is applied to it, it pulls the choke partway open. If this component is broken and the thermostat does produce spring tension in the push-rod, there will be too much choke action and the engine will stall (rich). NAPA Echlin 2-4824, looks like this:

You gotta get those '74 factory manuals, man!

Thanks, you're rigth, I gotta get those manuals soon. The part that I describe as unplugged and with the cable loose is the choke thermostat... I don't see any part similar to the choke heater controller, I think it is missing. I believe the choke pull-off is working; when I cleaned the carb, I applied some vaccum with my mouth to the hose and it moved freely moving the plate... I will check everything guys, thanks again.

Ed

Dan,
What are the titles of the manuals you refer to for this information? I have a CD (Detroit Iron) that is scanned from the 1974 Factory Service Manual, but it does not have part numbers. I need something with part numbers and exploded views, etc.

Jerry

Exploded views and part numbers are found in the Factory Parts Catalogue, which is indeed different from the Factory Service Manual.
