Weber IDF 40s...where do you get linkage and manifolds?, What do you know about CB weber update kits? Options

[computers4kids]

I picked-up a set of Weber 40 IDF carbs. I'm looking for the manifolds, air cleaners and linkage to get it all connected. Or where would buy these?

I currently have a set of Weber 34 ICTs running and connected. Can this linkage be reused/adapted?


The 40 IDFs that I just bought are freshly rebuilt with a Weber update kit from CB performance using this kit: Weber IDF Update Kit $134

This is what the PO had to say in the ad that I bought these Weber 40s in:
"Although they come with all the original jets, venturis, chokes, etc, an update kit from CB performance has been installed on both, opening up the throat to 44mm. The carbs have been re-jetted accordingly. A 12% power gain can be expected over a standard pair of 40IDF's, so if it's more power you want, these will do the trick." --What do think...snake oil commerical or hopeful thinking!

Am I crazy to put these on a stock (as far as I know 1.8)?



Thanks,
Mark

I'd go through those carbs very carefully and see what the PO did to them! I don't know how you put a 44mm "throat" in to a 40 mm carb! I'd go back to the stock 28mm venturi and stock jetting...ran good on my stock 1.8.
