2100 Question

[Deacon]

Well, I did some preliminary cleanup on the carb before I tear it apart.
Considering the amount of grunge its got I picked up a can of Gunk Carb Dip.
Here's the question. Not supposed to put anything plastic in the dip which means I need to pull the throttle shaft out after removing the 2 butterflies.

See any problem with this? There's a couple of plastic spacers on the cable side and don't want to screw those up. I've switched shafts on 4 barrel holley's before (20+ years ago). Sorry if this is a newb question. Just wanting to make sure.

I see no problem. The only piece of plastic on my 2150 that's there is a part in the choke linkage and the choke pulloff. Just take it apart and take off the linkage, soak the rest, scrub it with some old toothbrush, soak it some more, blast it with cleaner from a can, scrub it. etc. Might want to put a blowout protection check valve in the vacuum port for the poweralve, they're like $6.

[Deacon]

Yep, good suggestion. Guess my only concern is the screws holding the valves on.
The plan so far is to get it rebuilt and run it on my CJ5 304 and make sure it works.
Then take it down to Tennessee and hook it up on the J10.

don't remove the butterflies or throttle shaft! the screws are staked,and you'll damage the threads if you don't remove the screws correctly.
you don't typically remove them in a rebuild .the shaft is brass,or bronze,not plastic.

strip it down to the basic pieces,body,top,accelerator cover,choke assembly,and booster.also the jets and idle screws.remove all gaskets as good as you can,and pull the red umbrella from the acc. pump.

I agree. The only time you would need to remove the butterflies is to bush the shaft, and that's something a shop would do anyway. The butterfly screws are staked in place, and not meant to be removed.

[Deacon]

Yeah, the screws are "set". But there's a plastic spacer on the cable side.
That's the only reason I'm concerned.
I'd rather not remove the shaft. Just don't want to ruin that washer.

I may be just missing something simple. But it there a way to remove the linkage on that side of the carb without removing the shaft?

[Deacon]

BTW, I appreciate the advice. Sorry to be a bother.

[tgreese]

Point to it in your pic? I've never seen a 2100 with plastic parts that could not be removed.

[Deacon]

[tgreese]

Huh. I'll take your word for it - but I still wouldn't remove the butterflys unless the shaft needed to be bushed. Maybe dunk it so that the plastic part isn't submerged?

The dip isn't as strong as it used to be, because of the pollution laws, so your plastic part may not be in too much jeopardy. I think the cleaner used to be mostly methylene chloride, which you can still get (at least in MA) in pint cans as grafitti remover. In some states (CA?) you can't get carb dip at all without a license, permit, something. Maybe you'd rather go with spray cleaner and a stiff brush? Berryman's is pretty good.

This looks like a Ford carb - I've got one at home someplace, and I'll see if I can find it and compare and see what you're looking at.

[Deacon]

Appreciate it. It's off an AMC V8 but couldn't tell you where it started life.
I'll try to get a closer pic and post it up.

[Ristow]

i know what you talking about now,that plastic piece will be fine-throw it in the dip can.

[Deacon]

Kinda thought that. I've got another carb sitting beside this one. Not as nice though. And it doesn't have one.

[Ristow]

i've soaked a couple carbs even recently,that piece will be unaffected.

that is an AMC application carb too,it has the correct throttle arm and no ford kickdown.

Is that with or without gravy.
