1st Gen Rochester single barrel carb.

Hey all put a new carb on my inline six and I don't have the linkage from linkage on manifold to carb. Need a pic so I can make the linkage to connect the two. Thanks in advance.

I am assuming you have a '64 1st Gen from your photo & past posting.  '64 came with a Carter. The Rochester car had matching G-10 carb linkage.  Can you share a photo of your linkage? Just in case you have a truck carb.  I have a sketch to make a truck carb link that will then use the G-10 throttle hook-up.

Okay, now more specific to your question, I have a photo of the '64 style intake linkage - which is slightly different from later year. Also have mounting fastener reference.

PM your email so I can pass the detail over to you.

So you might have the newer Rochester MonoJet now,,,,,so here is some info on the Carter YF and Rochester MonoJet,,,,,,

So been looking around at cater yf carbs but none of them have the right accelerator linkage configuration. The manual u have does it give a full model # for the carb?

SmityG10 - I potentially have a fix for you - share a photo of your linkage.

Unless you got the throttle lever 180 degrees out.......


.

Yes

I've found every configuration for a cater yf except the one I need

so.....are you saying on your carb, the hole for the rod is by the valve cover like the one above that I had to braze a bar on to move the hole over towards the drivers seat so the pull down rod can connect to it,,,,,,,I think those are pick up truck carbs,,,,so you got a Rochester MonoJet or a Rochester B?

,,,,,and,,,,do you have all that linkage where the bottom rod pushes back, which pushes the middle rod forward, which pulls the upper rod down to open the throttle plate,,,,,,we will get this dialed in for you.......

Do you have the full id for the correct Carter yf carb

GF is the numbers guy,,,,,,,,,what size engine you got,,,,manual or auto trans,,,,,auto or manual choke?

I am working on a 65 with a 250 engine and this electric choke Rochester MonoJet seems to be working just fine.....

The original YF for 1964, 194 engine is Carter P/N 3821S

Also, the 3946S is an original option.

Just to add to the conversation. In donivan65's Post n°6 , it shows the linkage arm; unknowingly the arm is basically identical to the linkage mod I have made for other Vanner's with a truck carb. Like I stated prior I would be glad to share the simple drawing.

So tell me about this,,,,Rochester,,,,,,,where did you get it,,,,,is it new,,,,,what is on the van,,,,,does it run,,,,,,,is this linkage set up all there or it dont connect to your Rochester?

I had adapted the linkage on a Rochester which works, just trying to find orig carb, another fella gave me the full id
Carter YF 3857523. 3821S
Thanks for your help

I came close to buying one of these a year ago for a 250 in a C10, ended up finding the exact factory 1968 carb for it instead. After a careful refurbish it runs like a top. I've read a few horror stories about these, do you have much time on one to have a longevity report? Also does the linkage match up directly to factory linkage?

Fits right on,,,,,have to wire electric choke to ignition wire,,,,,need to use old air cleaner bracket or retap stud since hole is metric,,,,,starts way faster than my Carter,,,,,,probably 10 people selling this carb,,,,,,metering rod was not snapped into arm,,,,got wedged against float,,,which blocked off main jet and pushed float down and it flooded badly,,,,drove it around yard,,,,have not had it on the road yet.
