Post by: The Chaz on January 31, 2008, 03:35:40 PM

Go to Marc's house and look at his, or there are a few variations on eBay that you can look at for pics.

This is how it was hooked up before
There is an aluminum "s" shaped piece that I bolt to the intake it has a hold down that clamps the rod sleeve down.  then the rod attaches to the carb.

What I need to see is the place that the red cable connects to the carbs.  I have the linkage that connects them together.

Does this help?  Sorry about the messy photo but it's the only one I could find right now.

For a single carb it would work.  Do you have a single or double?

I am still setting mine up but here is what I have so far, and here is the cable clip you'll need. The only thing I am not to sure about is the cable has to loop up to connect to throttle bracket, and it kinda just sticks out there (oh shit handle for the backseat passengers) , I havn't actually hooked it up but I am almost sure I will have to bend or angle the  bracket differently so the cables arc doesn't hang out there to far.
Hope this helps,

So you can get the plate from Summit and it's a lot cheaper than one from one of the boat outfits.  I am making mine out of 1/4" plate aluminum due to the EGR hole in the intake  and I have to plug it off some way.  Later on I'll put a new intake on it but for now I just want to get it running so I can break in the cam.

Thats what scares me, it turned out so cool I just know something isn't going to work just right and I'll have to re-do it. I think thats why I havn't hooked up the cable and fuel line  ;D, besides I kinda like it sitting there on the entertainment center.

That's an expensive trophy for doing nothing but hooking rods and springs together.  :D :D :D  Looks cool though.   ;)

Just hook up your front carb like your single was and run the long rod between them, shitcan the rest of it.

I'm not an artist!

I think the designer of the linkage had this in mind
[attachimg=#]

and HDriderTH suggests something like this instead

Marcs is totaly different, his carbs are turned the other way, sideways.

I think the second diagram is the best way to do it.  I don't quite understand how the "T" works.

I have the same tunnel ram. Come over and take a look. Except my carbs are sideways.

Once all the stuff gets here (in the mail) I will mock it up.  If I still cant figure it out I will call you Marc.  Thanks everyone for the advice!  ;D

you can kind of see how i did mine, the linkage and cable connect to the rear carb and pull the front carb to open, so far i have had no problems with this set up
