PMO Weber carb linkage question
 

I need some help to know what I can use. I have a set of stock Porsche intake manifolds from a 70-72, 911T that carried TIN Zeniths. Additionally, I have set Weber 40IDA3C1's that rode on a set of PMO intakes in a 911 SC at one time. I sold off the PMO intakes as they were the wrong size for the intake ports on my motor. My question is can I use the PMO linkage with the stock Porsche manifolds with my
40IDA3C1's without issue? The motor is an original 914/6 type 901/38 beefed up to 2.2 liters with E-spec cams that will ultimately go in my 1975 914/6 conversion car.

The PMO manifolds are designed to use the Weber linkage. Zeniths fit onto the Weber/PMO manifolds without issue (just did this a couple of days ago when I finished off a Zenith project.) If the linkage was for Zeniths then you might be able to use it on Webers but Weber linkage won't work on Zeniths...not your question I know, just discoursing a bit. That having been said, expect to use PMO linkage on your Weber manifolds with IDA3C's without issue.
