Has anyone tried to apply the jetting tips from above to the 34 ich on a 3x1 set up ?
No, the Weber 34 is a very simple single barrel carb, and it uses its own set of air correctors and jets.
Its a very unlike the 2-bbl Holley Weber and Weber 32/36 carb. These Pinto/Capri/K-car/Vega carbs are far more plentifull, but have heaps of little differences, with something like 9 different versions from 1969 to 1975 alone.
I think the 34 Weber was used as a replacement carb for VW Bugs, some Opels. Normally Offenhauser, Clifford or Pearce supply jetting tips as part of the package. If you do a search, there is some information on these set ups, on this forum. It will take quite some time searching for it, but its apparently a very easy carb to calibrate.

I figured the primary carb would be larger with secondary or ouboard carbs being smaller. It looks to me that 3x1 works the same as the 32/36 so the jetting should be close or am I looking at this the wrong way ? John do you remember if the main jet changed with the idle jet ?
The idle jet is on the side of the carb and can be changed in seconds-it doesn't affect the main which is in the bowl of the unit. I had to go up a size or two on the idle as well as the main. I still believe that I could use a larger air corrector tube as well. For the idle jet, put one in that allows you to adjust the idle without going past one and three quarter to two turns out on the adjustment. If you go past that, you are too lean and need to go up a size. Remember to turn the outer carbs idle screws all the way in and to not power up the idle control solenoids on those two.

Do you recall what jets you used ? I have a ich in the center and ict on the outboards. I 'm looking for a baseline to tweek from the ich is for 4 cyl bmw and ict are a vw. So I'm sure it will be lean for my 200 .

i'm running 3 34 series webers and i left all the jets stock at first. i was getting starved for fuel and was having to choke it to get it to run smooth. so i jetted it up from 135 stock (i think) to 155 on the main jets. the idle jets are still stock and it runs just fine most of the time

ok now I have a baseline to tweek from. So
32/36 DGV 6 cyl 34 ICH 6 cyl
main jet -160 155 ( 135 stock )
air corr - 190 ?
idle jet - 075 52 ? ( runs fine most of the time )
pump jet 060 50 ?
the offy 3x1 with progressive linkage works the same as the 32/36 would'nt the primary jetting be the same or similiar ?
fattie64 where did you get your throttle levers ?
