After the poll about favorite carbs, I thought I should give the MC2100 another run. Once I cleaned it up and rebuilt it (and it's probably the cleanest carb I have seen in a while) I decided to improve the manual choke bracket. The generic one that is in the HELP section of my favorite auto parts store is less than adequate.

The design was inspired by HOLLEY. Let me know what yall think. [img]images/graemlins/cool.gif[/img]

My 2100 has a black circular cover over the side (The round part) that says lean and has arrows on it. Why is yours and mine different?

The black cover has the choke guts inside. I pulled the cover and stripped the guts out (you do this when you switch to a manual choke).

Normally you will find a thermal element like a coiled spring that expands and contracts to open and close the choke. All of that is replaced by a cable when you go manual.

Also you will find a lot of variations of the MC2100. Some have PCV ports, some dont.... etc.

That's the best pic of an MC2100 I've seen yet. Went to the Pull Your Parts( they still don't have T-shirts) and only saw one on a '78 Granada stamped 1.21 on the side. What model did that on come from and what kinda plug ins does it have? Those carbs are hard to find and I buy a new if I had a better idea what to ask for. Manual chokes are cool with me, less junk to mess with and reliable.

70's or 80's ford van E-100 I think. I have seen them on Crown Vics too.

if you buy new, ask for a 79 jeep cj with a 304

Bracket looks goods, you did block off the vacuum source right? Got mine off an 82 E-van with 302. Heard they can be found on similar pickups and Broncos. [img]images/graemlins/grin.gif[/img]

You never no what you won't find when you look for it. This link helps some, http://www.carburetorsdirect.com/ as far as applications. That yard has a lot of carbed Ford in the right years and engine sizes without carbs. Do you guys use phenolic spacers for hot weather applications?

Thanks,

I did have to block off 1 vaccuum port that let to the choke. I know of 2 poeple so far that had problems and "overlooked" the vaccuum leak at the choke when they went with the manual.

BTW

I put the carb on saturday and my manifold vaccuum went up. The Holley gave me 16.5 in at idle, the MC2100 gives me 19 in at idle. There is a small amount of "seat of the pants" performance gain. As soon as I run through a tank of gas I'll give the MPG stats.
