choking on multi-carb configuration question

[EstebanLoco]

I want to add more detail to the Strombergs on my current builds. I understand on a 3-carb setup that only the center carb has a choke - but what about the six-carb setup? Any help would be greatly appreciated.

Hey Stevie. I couldn't find any info on having 2 carbs with chokes ( 1 per side ). You might want to try giving www.vintagespeed.com a buzz and ask the guys there if that's possible..... Guido R.

Steve, I would like to be more help but I'm assuming you are talking about a "street" progressive linkage set-up? Shoot, I never ran more than one choke on anything and that was a cable (dash mount) mechanical choke. Never did like the spring, vacuum or electric set-ups.

Thanks Don,

I think I'm going to add the choke shaft (on the center carb) for the 3-carb flathead setup only and go with no choke on the 6-carb Pontiac. Besides, the 6-carb throttle linkage will be challenge enough. Thanks for the help guys.

If you've got a progressive linkage, only the center carb will open at the beginning. The other two kick in later. When is determined by the linkage.

So you wouldn't need a choke on the outside pair.

I would guess that a six-carb setup is more for racing and would not have any chokes. I'm sure more than one person ran six deuces on the street anyway.

Boy - would I like to watch you build up the linkage. I just can't handle linkages this small but if I keep watching people maybe I will see a way to do it.

Hey Steve, when you do it, can you show some pics? I want to do something similar but I have no idea what it looks like. I can get close but not accurate enough. With my knowledge, I'd hook the choke up to the emergency brake and not know what I did.

I will definitely post pictures. I have a couple of ideas. One is to remove the kit link arms from the linkage assembly and (once drilled out) use them. Another is to cut my own out of styrene . The latter would allow me to add the little pinch bolt (like on a battery cable). I have done these before at this scale with pretty good success. The trick is to drill your hole(s) first and then cut, file and form the plastic around the hole to the desired shape. Some of you may recall I also used this method for my batwings and interior door handles.

I also have some ideas for the spherical ends. The nice thing about adding this type of detail is that a little goes a long way. That is, any improvement over the bulky (and slightly out of scale) kit linkage would be nice.

I've attached a few drawings of how the drill first - then cut out method works. Material is bar stock, use your nibbler for major cuts, file to shape. Make the pinch bolt cut with a sharp chisel blade or jewelers saw.

Way to go Don!! You read my mind

I played around with the linkage today. It is definitely easier to use to kit ball bearing rod ends. Just cut them off the kit linkage and drill them out. Links that aren't from the kit were made from sheet plastic. I used the kit radiator support rods for the linkage. The throttle shafts are 00-90 screws that once screwd into the links I cut the head off. The rest of the hardware is sewing pins. I can see room for a lot of improvement but this was a fact-finding mission.

Note that I had to bend the linkage on the 6-carb setup on the passenger side to clear the distributor.

Stevies' definitely back and as hot as ever. Leave it to Steve to set the bar height for this set up. This answers a billion questions I had. Thanks Steve. You're back to your old inspiring self.

Oh, yeah...............
For you guys that are new to the site, keep on eye on Steve's posts, his builds are some of the best my tired old orb's have seen.

multi carb choke(s) in the 1:1 world 3 deuces used single ckoke on center carb. start with progressive linkige on ceter carb open only. you could use automatic choke but you were ahead of the game if you used manual. on 4 or more carbs progressive linkage and chokes just did not work, you used a primer for cold starts(starter fluid, eather). hot restarts you had to be lucky.

Thanks j.f. This is one area where my knowledge base is zilch. The more info we can get on this kind of thing, the more realistic we can make our details.
