140 carb linkage?
Posted by: Squirrel40 ()
Date: June 06, 2014 03:25AM

Does anybody have a closeup picture of the carb linkage on a 140? I am currently replacing my carbs and I think I have it right but want to double check.

Hopefully in the next few weeks I can hit up a few car shows and maybe find some Corvair guys that are local so I can bug them about all my questions grinning smiley . If you are close to Marysville Ohio and want to help out a rookie let me know.

Steve, the picture doesn't show the actuating rods very clearly. I have the same problem as the original poster. It gets further confused when you start looking for parts.

I don't have the parts manual at my finger tips, so I checked the NOS section of Clark's online catalog. They list a different actuator for every carburetor on the 65-140 setup. The only one I am certain is correct is the primary, driver because it has the c-clip. A couple of clear close ups of the actuating rods on the 65 setup would be helpful.

Are both the secondary actuating rods actually that different? Both are connected at the same place and both are pulled upward by the swivel arm.

Also, is the actuator on the 65 140 passenger side primary any different from the same actuator on a 95 or 110 engine?

Any help would be greatly appreciated. Thanks in advance

First assumption you are asking about the early 1965 140 linkage?

If not, the following probably is not correct.

Are you talking about the rods from the cross shaft to the carb?

On a 140, they are all different from each other.

I would assume that the primary carb rods are the same - 2 carb or 4 carb.

I assume that the rods will work correctly (not bind / whatever) only if they are installed on the correct side / carb.

Here is a pic of early 140 linkage (not for sale) - two rods on the right are primary (I think):

Robert,

Yes, I am referring to the 65-140 setup. So, all four are different, eh? Wowzer, doubt if I have the correct rods, but your picture helps plenty. thanks

I'm guessing the two on the far right are for the primary? I do have the correct rod for the driver's side primary. It has the e-clip. I will have to go though my box of carb linkage and do my best to match the others. GREAT PIC.

I think the 2 down links from the lever to the carb are the same on both secondary's?

You would think so but Clark's list different rods for all four. If you look at the levers on the secondary carbs, they both pull up and both attach to the carburetor in the same location. I think the bottom line on the secondaries would be: do they both start to open at the same time and do both reach full throttle?

I suppose it is possible that the levers are at slightly different angles requiring longer or shorter rods.

Why doesn't somebody invent a cable drive system????????????smoking smiley

If you look at my first pics the rods look the same, I do have a Complete set of 140 chrome linkages I got from clarks 15 years ago,,but I have the parts spread out on 3 different cars! LOL

I agree Dave, they sure look the same. The only thing I can imagine is that when they left the factory with the correct rods, the levers might have been at a different angle, maybe to help clear the air cleaner? After 50 years it's hard to tell.

Like you, I can't see why you couldn't use the same rods for both primaries. Now to to go out into the garage and see if my theory holds up.

Well the pass side primary down rod is a solid part and the drivers side primary is adjustable like in Roberts Pic,so you can balance them,then you adjust the secondary push/pull rods to get the secondaries synced up, and the secondary's should open at the exact same time and reach fully open at the same time.

That's always what I shoot for. I don't always get it right the first time. Three of my rods looked like the one's in Robert's pic. I'm having trouble finding a drop rod for the pass-primary. I'll find one or scrounge one up somewhere.

Too many bugs out there now. Why must they always fly into my face? Can't they just fly into the light and die?

Cliff, go to Ace Hardware and get No Natz. You spray it on and those pesky gnats will leave you alone. Smells like a citronella candle though.

I'm afraid all our Ace Hardware stores have gone the way of the Dodo bird. I grew up in Sarasota, FL and thought we had a lot of bugs there, but we've been getting a lot of rain here lately and every single bug in the state seems to think it's mating time. But hey, not in my nostrils. moody smiley

FWIW, my GM parts book shows two part numbers for 65 - 66 secondary down links

3.752

3867211 LH
3867212 RH

Well, davemotohead is correct, too

Did a search in gmpartswiki and came up with a book that shows

the above two part numbers as

1965/ALL
1966/ALL FIRST JOBS TO SERIAL NUMBER 000556

and part number 3880757 (2) as

1966/ALL AFTER JOBS FROM SERIAL NUMBER 000557

Looks like there were other differences in 1966 secondary setup based on the same serial number split - springs, support assembly

I have Roger's Heim-jointed linkage on my '65 140 and like it a lot. I had to do a bit of tinkering to get everything setup to my satisfaction, but once set, I've not had to touch it.

Well, you are the third person including Roger Parent to mention that in this thread...

But, the thread is about setting up the stock linkage...
