2100 quiz

Here is the story. I have a 79 CJ7 with a 72 304. It has the 2100 carb that must be from the 79 because it has an adapter to fit the smaller bolt pattern on the 72 intake. My other 79's had electric chokes. This choke looks like the electric but it is not. Instead it has a little metal bracket attached to the choke where the heater hose coming from the core to the back of the intake can rest in. As the motor warms the hose it then heats the choke. It works great[img]/wwwthreads_images/icons/smile.gif[/img]. Also my others had an electric solenoid for a throttle stop and this one has a regular screw but has a dashpot. Here is where I am puzzled[img]/wwwthreads_images/icons/frown.gif[/img]. I thought I would put a new dashpot on and when I went searching I would take the carb number which is 5DM2 and it is very clearly stamped. The parts stores told me that wasn't a valid number[img]/wwwthreads_images/icons/mad.gif[/img]. I went to Wrenchead.com and they showed 6DM2's up to 9DM2's. My question is what might this carb be out of and does anyone else have this type choke on theres? Oh yeah it has that 108 in a circle I've heard some of you talk about and does anyone have any suggestions on where to find a dashpot thats not so expensive?

Fullsize Jeeps in a junkyard might be a good source for the dashpot and bracket.
just a thought.

all of the 2100s/2150s Ive messed with had the hot water choke.

Re: 2100 quiz

The dashpot on the BBD is used so that if you let the throttle slam shut the engine won't stall. Set up right it makes the linkage slowly go shut at the very end. Thats probably why you have it also. If you can't find one, when driving remember that it could stall if you take your foot off real fast, panic braking?

Re: 2100 quiz

Thats the kind of choke that is on my '77. I just cant get my choke linkage to work right, it wont kick down after it warms up. Dont know what to tell u about the dashpot though. Good luck.

That's definately an AMC code. In my book "Motor" 1973-1978 it lists the AMC carbs made by Motorcraft for their automobiles. It shows all 5D's as being 1975 carburetors. It has 5DA2, 5DMS and 5RMS all as 1975 AMC automobiles. All the Ford Motorcrafts had a D as the first digit, so it's not out of a ford. Must be a 1975 AMC truck carb in origin.


84 CJ7, 258, HEI, M/C 2100 carb, 5 inch lift, RS9000's, 33x12.5 BFG M/T's, Lockright, full cage & belts, Xenon flares, AMC 20 1pc axles, GM dual diaphragm brake booster
