Please help me with a super frustrating problem that I can't seem to find anywhere else.
A 200 cu. in. straight six resides in my 1964 Mercury Comet which is a brother to the Ford Falcon. This engine originally used the hunk-of-junk known as the Autolite 1100 coupled to the even-bigger-hunk-of-junk Load-O-Matic distributor. Sometime in it's life, this car went to the dealership and received the Holley 1940 carburetor as a service replacement part as denoted by the tag affixed to one of the screws.
Therefore...in relation to the Holley 1940...How do I adjust the choke/fast idle rpms independently of the overall idle rpms?
I know people normally just turn down the overall idle screw but that causes me other issues...When the overall idle is turned up, the choke/fast idle rpms tend to run super high like the engine is running away. Yet, when I turn down the overall idle screw to compensate for the fast idle, the engine tries to stall at traffic lights during normal driving conditions. Otherwise the engine runs just fine.
So. How do I lower the fast idle speed while retaining the overall idle speed?
FYI. I learned in diesel world so carburetors are not my specialty and I really don't understand the myriad of linkages all over this Holley 1940.
Thanks in advance.
