Thanks for your reply JimH.
I would like to keep the original automatic choke but it doesn't seem to want to cooperate.
The piston was frozen and I did manage to free that up. The water lines in the choke were gummed up with debris. I cleaned that up too.
However, the while the car runs well. It typically idles at about 2,000rpm initially and then it slowly creeps up to about 3,000rpm. If I manually play with the choke I can get it down to about 1,200 RPM and it stays steady until I give it some gas and then it returns to an idle of about 2,000 rpms again and then creeps up. tapping on the accelerator doesn't cause it slow done. I have used the two adjustment screws and that hasn't made a big difference. Sometimes it is difficult to start and if I make manual adjustments, it starts quickly. The butterfly valve is clean and does not stick in one place. So I am thinking that I want to go to a manual choke.
I also am contemplating removing the deceleration valve (as I have been advised by several folks).
I thought if I had the manual choke then I would have more control. I did buy one of the kits by DORMAN but the parts don't really fit.
Thanks for your input.
