Look at the driver's side of the carburetor to see if there is still a silver or gold-colored metal cover held on with three rivets. Holler back when you have that info.

Well, it looks like there may have been a metal tab at one time, a tab end held on by a single large rivet as far as I can see. There is a lot of hardware on that side though.

If you can see all that stuff, the cover has been removed long ago. Three rivets had to be drilled out to remove it. If you look closely at them, you will see at least one of them has a 10mm nut under the remaining part of the rivet. Sorry, but I'm doing this from a tired, old memory. The one you're after, I seem to recall, is the one that's closest to the front of the car. Loosen that nut. That will allow you to rotate the curved adjuster for the automatic choke. I think you want to push it as far toward the rear of the car as possible to the end of its limit, then tighten the nut.

The thermostatic spring on this carburetor is so strong, it will raise cold idle speed without you having to tap the gas pedal to set the choke. Adjusting the choke will stop it from overloading causing black smoke out the tail pipe and fast idle speed will be lower and come down sooner.

Well I finally loosened the arm holding a (what appears to be a neoprene) gear that runs along the top of the curved adjuster, shoved the adjuster forward all the way and let the neoprene gear ride the adjuster back. Seems to have slowed it down a good bit. Will keep playing with it some more as time permits. Thanks and any more advise will be greatly appreciated. My email addy is discipleofyahshua@inbox.
