Can someone measure the actual side to side venturi of an FCR35 near the needle? Is it 35 or 34mm? I know the adapter and area near the velo stack is 35 but the venturi looks smaller (I don't have one on hand to measure).

I should add that I didn't have the measurement for Jim, so if anyone does, please do respond to his question. Tx - B

Jim, what is the ulterior motive for asking?

Would be great if SUDCO was still down in California to answer the question.
