Re: IML: Choke Heater Stuff...

Elijah:

 

You're just the guy I was looking for!!  You seem to have positively identified this choke set-up with a Mopar application.  After your coffee, and any other morning rituals you may have, if you could confirm the proper places to run each wire, I would greatly appreciate it.  While the car that this old Imperial motor is in, is a 300L, I know it has a ballast resistor - it should work out just fine.

 

I still don't understand where the thermal-spring gets it's engine warming data from, though.  Unless the constant 12V from the ballast resistor is just to "help" heat the spring, and it uses the ambient temp. next to the carb to adjust the choke slowly.  Regardless, the proper hook-up is all I really need.

 

By the way, I have about 15 different carbs in my stepfather's basement from mid '60's to early '70's Mopars.  A few AFBs, 4-5 AVSs, 4-5 Thermoquads, and a few Holleys.  With all the help from the Imperial Club, perhaps someone is looking for a certain carb they can't find.  Let me know if that's the case.

 

Thanks again everyone,

 

Dan Richardson

Now, that begs the question.... does anyone have this choke disk on their Mopar?  If so, where do the terminals connect?  Or, if Chrysler never used this set-up, where can I purchase the 1- Well type choke set up, 2- a new vacuum choke pull-off, 3- the proper linkage?

When I rebuilt the engine in my '71 Imperial (http://www.imperialclub.com/Yr/1971/Scott/Engine/), I replaced the original but broken Carter AVS (the body actually had a big crack) with a new Carter AFB with an electric choke.

The carburetor you've described has an electric choke, which is generally "better" because it's more reliable, AND it's adjustable.  It also heats up faster, allowing the choke to open sooner, getting the mixture leaner quicker after start-up.

I seem to remember that the hot wire for the choke was connected to the ballast resistor, so that the choke would only be activated when the ignition was turned on.  I h aven't had quite enough coffee yet this morning, so I may not be remembering correctly.

There's an excellent, excellent book on Carter Carburetors that I highly recommend -- http://tinyurl.com/hjgwz.

Good luck,
