linkage issues

[Janksun]

The linkage in my 510 is not cooperating. I bought the car non running and the linkage was apart when I got it. But Idk how it's supposed to go together. I've tried pretty much everything I can to get it to work. Next thing I can think of is just fabbing up something that will work.

 

 

If you look you can see that if I push the gas pedal, it will push the arm to turn the thing on the carb the wrong way. Is there another way to make this work or no? Everything else I've tried has not worked.

[Janksun]

Can anybody help?

[Janksun]

I need to get this figured out..

[datzenmike]

Doesn't look like a stock carb. This could be why.

[Janksun]

It's a weber. Sorry forgot to add that.

[ggzilla]

Yes, convert to a cable instead of using the stock bell-crank linkage.

Mine rotates backwards just move your arms around ,, it will do it ,, you just have to move the rod to over the linkage. Been running it like this for 3 years because i used a 5200 carb as it was all i had.

 

MINE taken a minute ago

 

 

couple more to show other than that it's the same.

 

 

 

 

Is that what you ment??

[Janksun]

Kind of. I cant really move the part that connects to the carb because it puts it in a weird spot that the arms with the balls can't reach.

[Janksun]

I just moved it to make it look like yours, but the hook looking arm doesn't sit in the thing on the carb right

 

 

And I can't turn the thing on the carb because it's slotted for the stud that comes out of the carb

[bananahamuck]

Oh i think i see,, can ya weld ?? get a extra linkage arm (long part) from the Keeper ,, cut one end off then rotate to where you want then tack, pull out and finish weld. Oooor if no welder at car,, match up and use felt marker and weld at the Keepers when you go over. It don't have to be perfectly straight just in the right location,, rotation wise.

 

I would just risk it and use the one you got,, no matter if it takes 2 tries there is very little risk of messing it up permanantly.

 

?

[bananahamuck]

Wanted to add that my carb didn't have nut on linkage to bolt on bracket, so i welded my bracket straight to the carb linkage, in so doing i was able to put bracket where the rod was , but i had forgotten that part.

((EDIT)) before you cut
I went back and checked out my build and it looks like my linkage was in the up and down position when done. almost like yours needs to be to slip into holes.



Is your gas pedal sitting on the floor??

Shouldn't the shaft coming off the firewall going to the carb have the arm controlling it below and not above?

[ggzilla]

Bolt a stock Datsun 521/620 carb quadrant to the Weber (or buy the Weber quadrant) and use a cable. The quadrant can be flipped for RH or LH operation.

 

Do you have the Weber DFV (LH version of the 32/36)?

 

Holley 5200 = low CFM Ford version of Weber DGV

Holley 5210 = low CFM GM version of Weber DFV

[Janksun]

I don't have a welder, and I'm 2 hours from the keeper :/ but I do know who has a welder close by :) maybe I'll have a buddy weld it for me

The linkage is in the floored position in the photo, if pulled back to the idle position, and the shaft control arm put under the shaft, would that not drop the shaft straight down through the carb linkage?

[bananahamuck]

Yes,, what WAYno said ,,, as i added more to my earlier response  showing mine is almost in the right spot ..

[Janksun]

Idle position is pictured below

 

 

Floored position is pictured below.

 

 

If the arm coming off the firewall is supposed to have the shaft below it, like pictured, and I were to press on the gas pedal, it would turn the carb the wrong direction.

 

Picture this sitting in the driver seat. To give the car gas the thing to turn on the carb has to rotate clockwise. Idk if this is normal or what, but this carb is just what came on the car.

[Janksun]

It's a 32/36DFAV

[wayno]

OK, looks like the way it should work, it's the way I would design it, maybe they make a carb that twists the other way for this vehicle you have.

Can the carb be turned around and controlled from the other side?

[bananahamuck]

In a perfect world,, your supposed to have a butterfly that spins in the counter clockwise direction,,, but  i go with what i got as i'm not made of  money.

 

here's mine rotating in a clockwise direction. 

 

 

[Janksun]

Wayno, if I were to turn the carb around I'd still have to fab something up. So might as well make this work.

 

Bananahamuck, thanks for the video, it's very useful. Oh and nice feet! Lol

 

I think what I'm going to do it heat up the arm that goes from the firewall to the carb and bend it until it works.

[wayno]

If you turn the carb around, it then will be opened the opposite way, but that doesn't mean it is even possible with that carb.

When you put the arm over the shaft with the pedal in the idle position, I take it shaft doesn't line up with the holes?

The photos you have posted all show the linkage in the floored position except the last photo, so I can only imagine/guess what position it will be in, to me it looks like it might be close, but I have a set of linkage out in the garage right now, and it doesn't like to be lifted very high without binding.

I have not had a 510 in several years, so this stuff is getting fuzzy to me now.

[Janksun]

In only one picture the linkage is floored. And that is the last one. All the others are at idle.

 

If I put the arm on top of the piece that runs from the carb to the firewall just like the picture below,

 

 

It ends up like this in idle position

 

[wayno]

EDIT

I guess I don't remember any of this anymore, and I should but out.

[EricJB]

It's a 32/36DFAV

 

DING DING DING!!

 

The correct carb for your Datsun is a DGEV. A DFAV ( same as a DFEV but originally with an aqua choke) is pretty much a mirror image of a DGEV, and was widely used on 1st gen Rabbits and Scirrocco's. And the throttle swings the other way, if I remember correctly. Get a cable or a DGEV.
