Maybe he meant THIRTY eight mm 'chokes'? not 48mm (to be honest even 38mm chokes are on the large side of things, unless it's a fairly hairy cam/head combo??

Beyond the fact that they are 45dcoe webers, what model are they. There's actually a couple of different types, the 9 the 13 an the 152 (?? I think it's the 152). they have minor differences in idle and transition fuel discharge holes. IIRC the 152s are actually the ones made after they stopped original production, and started being produced somewhere like spain?

The differences appear minor, but in practice it's a huge deal (for most people) and generally speaking the dcoe 9 version is the one everybody 'wants' the most.

It's also (naturally) important that they are both the same model, because with the same jets/bleeds etc, different models won't behave identically, and can be a hidden tuning/optimising pitfall.

Reason I'm posting all this is because it'll be essential to know which model dcoe they are to have any idea of what an appropriate $$ offer might be (or whether they are suitable for whatever combination a potential buyer might have in mind).
