It’s finished! I blogged earlier about my Autolite/Motorcraft 2100 carburetor with the malfunctioning choke. The carburetor is done, and as it turned out, it was a multi-part problem. The first issue was the vacumn pump wasn’t functioning properly, and needed some serious help!
The next issue was that the spring coil for the choke was rusted out and not providing adequate tension for setting it accurately. The solution I came up with was a replacement of the choke cap with an electric choke, eliminating the need for the manual driven vacumn completely.
Although the vacumn pump works properly, I decided that the electric choke will be much easier to manage, and it requires 12v power, so a quick wire running to either the “s” post on the alternator or the auxillary connection in the dash wiring harness should do the trick. In reality the electric choke should only require full power at start-up, so I’m not too worried about power drain on the battery. The only thing to be careful of is to make sure it is not directly connected to the battery, or else that 12v draw would slowly kill the battery!
The final issue with the carburetor was that the jets inside the carburetor were clogged, preventing the engine from getting enough gas on light acceleration. That was cleaned up, all of the gaskets were replaced, and the entire carburetor was stripped and re-plated to get rid of the nasty blue paint over-spray that the carburetor suffered what the engine was re-painted. (Whoever used to do the engine work on this car didn’t seem to concerned with doing careful paint work.)
I’m planning on getting the carburetor back on the car this week, and in the meantime I’m busy working on the air cleaner! I’ll post photos of the restored cleaner as soon as the paint work is finished!
