Rebuilt my IDF and installed bigger 32mm vs 28 mm venturis and now it wont flow fuel


If I spray carb clean in the mains and bowl vent I can get it to squirt fuel into the barrels but once that flows it wont feed any more fuel, thoughts on what i put back together wrong.


Also I notice my spare parts had like a bunch of different sizes of diagraphs for the accel pump, why is that

If its not flowing fuel check you floats settings.... Or pull top off carb and see if float bowl has fuel.... Is fuel pump actually delivering fuel to carbs?

As for the different accelerator pump diaphragms, Weber changed the design several time over the years and the reason you have extra diaphragms is you have to select the proper one for your particular version of carb and keep the rest for dust collectors or trade or.... The carb kit is a universal fit so there will be some extra "stuff"...

Yes because it was leaking at the hose at first till i resecured it.



The gap on the float was 10.4 and 25mm btw
