The Stovebolt Site Forums The Shop Area Engine Shop 235 with duals (linkage issues)

I just spent the better half of 2 days trying to re-adjust my linkage after switching over my dual Rochesters to dual Carter W1's. The stock 235 linkage arm now appears to be too long, and will no let the Carters bottom out for a better idle. I've seen an aftermarket stainless linkage arm on e-bay this week. Is this worth the $65 they are asking? Anybody have one? Does it actually fit properly up and inbetween the manifold and exaust headers? Anybody have issues like this? suggestions? http://s537.photobucket.com/albums/...=BnSt7rBGkKGrHqIOKjIEtkoKdqeuBLi7rQO.jpg

I do not know what is at the top end of your rod, but I have used this rod with a dual-carb set-up.

It bends easily and has the right diameter for connection to the bell-crank on the side of the block.

yea, same top end as my rod. (1957 stock)

The rod should never be bent, even for clearance.
If there's no other way (that's what bell-cranks are for) it has to be really thick or throttle operation will just re-bend or unbend it.

will no let the Carters bottom out?
Does it over-travel (still have available motion after full throttle)?
Yes: lengthen the rod.
No: the rod isn't the problem, the ratio of rod travel to throttle shaft rotation is wrong.

I see no other choice for me but to bend it at the tip . The rod is simply too long. Its not letting my carbs bottom out for idle.

I've used a bent rod of the same diameter with single and dual carbs for many decades (since I changed to a 261 in 1971).

OK guys, update:
after much thought, I bent the tip of the rod to meet the linkage. Runs perfect. Hardly noticable unless you stare at it.
