I have a Rochester 2BBL carb that was not designed for a car. I don't know original application. Rod for air filter is angled forward, not straight. Throttle rod connection is a grommet, not carb clip. Carb is not newer than mid '60's. Carb vents gas fumes from bowl to atmosphere at idle.

A picture or two and any numbers on the carb would be a big help in this quest.

As mentioned , foto(s) would help . . . ( esp of any number(s) you find on it )

Sounds like a tractor carb. Get some pix up!

This could be a tractor carb. Pics show carb throttle rod connection similar to tractor. Notice air horn angled toward front, not straight. What application would have angled air cleaner?

A boat?

It's a 2GV, used in the mid sixties (only a few years in the US). Might have been more popular in other countries - I'm thinking south america.

I talked to the guys at Mikes carburetor, carb is 2GV, from 64-65 chevy passenger car.

Never saw one with the tilted air cleaner stud boss, but maybe that was post-factory

Ok - - - - set down , grab a cool - one . . . . . . . . . here's my take & worth completely nothing ;

I agree = "Rochester 2GV , 2bbl , from mid 50's (was on 55 Chev 265 - V-8's , 56, 57,58,59,60,...…….
and, so many more GM's cars / trucks ).
Kinda like the "standard GM 2bbl - Chevy carb" .. . . . . . . .

Then - "the bent part - - - happens - - - when you 'try to remove your air cleaner" (those old "oil bath type
air cleaners) . . . . without completely removing the 'wing-nut' . Then, you just install a new 'all-thread'
and . . . . tweek too fit. Almost all the throttle-rods , mounted that way - - - - - - back then .
can you spell . . . . . . . KISS - - - keep it simple ****

Like ….………………………….. old school...…………. man ………….. with poodle skirts . . . . . .
or "penny loafers"



look at the picture - again - early Chevy (GM) p/u truck . . . . . most likely early 60 / 65 , somewhere
in there . Maybe - - - - a 283 , even .

again . . . . . with th' LS Jim .

(ps - - and, I could be completely wrong ) .

Twin, your reasoning doesn't explain why Rochester carb put air cleaner rod at an angle, not straight. I've had carb on my garage shelf since mid '90's. My '66 C-20 with original 283, manual transmission needed a working carb. So I rebuilt that, put on engine. Engine runs better. Carb # shows application for 64-65 Chevy car with automatic trans. and automatic choke. Gas pedal linkage is different for automatic and manual trans. My '64 Nova 6 cyl with powerglide (also original) verified difference. So why is air horn angled? Not straight.

The reason for the carb stud being bent is, somebody eons ago, bent it to fit some off the wall air filger, NONE were done that way off the shelf. Now, there should be a 7 digit part ID number some place on the carb, or, if still there, a bolt on tab on the carb top, post that, please, we can nail the ID down if it is in one of the publications available, or on a web site mortec.com. Example: 7027103, 1967, Pass, Chevelle, Chevy II, Camaro, 283/195 hp, A/C (air cond) w/o A.I.R. (air injection reactor).

My guess = is that you are using a "later style air filter " - - - not the original type "oil - bath air cleaner" .

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Then , read " Old Man 's " post above . . . . . . . NO Rochester 2 bbl carb - came that way . . . .
someone = somewhere = back in time = bent that "cross bracket" (for some reason) ………………….
then, left it that way . Maybe because - - - - If You Try TOO BEND it Back = you could break it - off .
………. not a good idea …….

[Twinshadows]

I can also guess - - - - - It's NOT a Tractor ………………..

Chev standard 2bbl carb - - - used on BOTH -- - - Cars & Trucks .

Most all tractors have 1bbl carbs . . . . . . and , most are " up-draft type carbs " .

(but, anything - will - could - and has been done with sbc , and 2bbl carbs ) . I've got one in my shop
for one of my 250 - 6 motors , mounted on a " Clifford 4bbl Alum. manifold " ( Rochester 2GV carb) .

Carb # 7024110 all the pics I've seen show straight rod. Why did Rochester angle this?

anyone else need an aspirin after trying to read this?

 

[AllyMcReal]

Either Rochester bent it to fit it onto Mr. Benny's Maxwell, or Rochester never really bent it and it was manually adjusted by some owner, or even dropped once with the air cleaner stud in it, but didn't break off. I asked a carb expert friend of mine, and he can't ever remember seeing one with a bent air cleaner stud mount like that one.

Carb was cast that way. That top section of carb is all one piece. I can't explain it either, but there it is. Every Rochester 2bbl carb pics I've seen have straight rod for air cleaner. So why would Rochester design, build carb with that angled rod?

 

[kt64]

these are pics of both carbs. Black linkage is new carb, straight air horn. Other carb has angled air horn. Why would Rochester design and build angled air horn? Air horn is cast into top piece. It's all one piece.
