From what read on line, an auto choke can be converted to manual using some parts from the 2100 two barrel. Copied here from gearheadtalk.com:

1. Unscrew the butterfly screws on both your carb and the donor 2100 from the main throttle shaft.

2. Remove and swap the throttle shaft, replacing your butterflys into your carb and the old ones back on the old 2100.

3. Remove your choke housing from the 4100

4. Remove the choke linkage from the 2100 and install on your 4100

Once everything is all put back together make sure screws are tight and clips are on, you should be good to go. A very inexpensive way to get the HIPO look, to eleminate the auto choke housing and to get the correct linkage for a 4 speed car, if you want this type of conversion. If you have any questions or need pics of what i am talking about, email me at
