What is the purpose of the coolant tube that runs through the Weber DGV 32/36 manifold? Is to heat the mixture, cool the manifold to compensate for heat rising from the exhaust manifold, or has it something to do with a Weber-idiosyncratic operating principle? Here's the deal: I am thinking of using one of these manifolds, after some adaptation, with a Solex Pict 30 carb on my B9 (B18:2) powered generator project, which you may recall my Nov.18 post, and I'm wondering if I could get away with not routing coolant through the manifold. I have a spare set of SUs I could use, but I'd just as soon keep them for real Volvo application.
