How did you do this? Drill and tap the arms?

I need to do the same thing with mine.

That is a bell crank linkage and it uses the ball on the carb linkage.


I know that, silly. (IMG:style_emoticons/default/biggrin.gif) I've got the same linkage. The issue is that the bar between the linkage and the carb butterfly lever is at an angle. In fact, they are at slightly different angles. If you use the provided holes in the linkage arms, you will not get a 90 degree drop on either side, and the carbs don't stay perfectly synched through the rev range.

They're both parallle, its just the angle of the picture that is making it look out of plumb.

In this thread: Show pictures of your dual Weber setups. The more detail, the better.

Dual 40 IDF's - CB Crossbar kit, with extension on passenger side throttle linkage to keep them parallel and sync'd.

Cargeeks is the best linkage so far, but still a bit too much angle on those droplinks for me.

Found this ad on the samba, I had to laugh....build the f'in linkage right in the first place and you don't need this shit! (Sorry Type 1 again)

This car ran for about 5-minutes after the engine rebuild. After posting this same picture back in 2007 many of the carb set ups on this post mentioned the set up was not the best. "Money Pit" is still on jacks.

One day I'll finish my contracting work in Afghanistan to finish her up; she will rock!

I had that same set up, you can never get the links to go right. they stick out way too far.

CB linkagewas better, but we modified it, too... moved the drop links closer to the carbs and lowered the bar lower than the lowest pre drilled hole, now it is 90 degrees at the top and bottom. very straight

someone here makes a nice pivot linkage I'd like to try, like the cb setup. i think it would be better than the hex bar.

There is alot of talk about getting a 90 degree drop. I hate to say this but it'll never happen. You might be able to get 90 degrees at one throttle position but thats it. The hex bar spins in an arc and your looking for a right angle. You can't get there from here. Whats important is that both linkage arms are the same length and at the same angle relative to one another. That way the arm travels the same distance on either side. If you get that correct the carbs will stay synced through the entire range.

I believe that is called the sidewinder linkage kit.it's set up similar to a 69 VW type3 I had with dual solex carbs, a side twist linkage setup that bolted onto one of the case rib bolts. Had small ( 4mm IIRC ) left and right threaded ends for adjusting the carb butterflies / throttle plates linkage bars. Just had to get them bouth the right length + / - a few threads. Wasn't real hard to get them both synced with an old unisyn . (IMG:style_emoticons/default/smilie_pokal.gif)
