Ok, so I have what I think is a MC2100/50. BUT! It has absolutely NO markings!!! So I guess I don't know what I have. So I went and picked up a Holley 2300 series #7448-1. It's a 350cfm 2 barrel with an electric choke.

Problems:
#1) The throttle linkage is designed to pull back, not down.

I have a linkage adapter from the previous carb, but I haven't sized it for fit yet. I'd love to hear any other ideas of how people have solved this problem before.

#2) The throttle linkage contacts the booster vacuum line.

It only hits by like 1/16". I've considered modifying the linkage to allow for the clearance. Or, I could buy a taller spacer... Haven't decided yet. Ideas?

#3) The electric choke isn't hooked up.

I don't think the CJ7 came with an electric choke. Do I just supply the thermostat with +12V? It has a ground wire already attached to the carb housing... and yes... I'm going to make sure it's a solid ground!


I'll take any and all ideas and let you all know what I settled on and how!

OH! ...and BTW, It does run! Idles high, but it runs and I haven't adjusted anything yet! :eek:

Thanks

# 1, reroute the throttle cable
# 2 get a taller spacer
# 3 I will have to check on that, do not know how an electric choke works
 
1. The stock carb on your L6 was a pull down, you have 2 options, fab a new throttle cable bracket, or buy one.

you can buy one specifically for a Holley from Summit or Jegs or anywhere else online

2. This will probably change with the new throttle cable bracket. If not, carb spacers are only $20 (ish).

3. Find a +12VDC source on your fuse panel, the only thing is the +12VDC can only be on when the key is in the RUN position. Just run a wire straight from the fuse block to the carb, and like you said, double check your ground :D
