Running Cold

[FLATBEDFORD]

I think it is the bi metal spring. In the summer it works OK. In the colder weather it seems to stay open. I replaced the heat tubes with copper tubing a few years ago. I'm thinking that going electric would make it easier to deal with.

I installed an electric choke on my 2100 carb works great 20 mins work to install.

Holley sells the cap #45-258 then you run a ground wire to a screw on the choke housing, then run power wire to the alternator stator terminal marked "S" at 12 o'clock-ish position on back of alternator. (made my own wires and connectors) The stator is only hot when alternator is running. Perfect!

Hope that helps.

Thanks, OldGuy.

I don't have the part number handy, but I just ordered it off of the AutoZone website. If you look for the choke thermostat for a 74 f100 with the Ford carburetor (Autolite 2100) you should see it. there is only one available on the site.

Now that I have the choke adjusted properly and the idle mixture right it works great.
