<p class="MsoNormal">Here’s an interesting article on various carb choices for the BMC B Series engine, which I think would be fairly analogous to the TR2 through TR4 engines. It covers the 32/36 DGV, the 45DCOE, and the variations on the H4 and H6 SUs.<o:p></o:p></p>

<p class="MsoNormal">Well, having written what I wrote, I did a little research and found that someone is actually offering a dual 32/36 DGEV setup for a TR7. So maybe it’s easier to do than I thought. I would think this would be a lot of carb for this engine,
however. <o:p></o:p></p>

<p class="MsoNormal">I don’t know a lot about Weber carbs, but I believe that these particular carbs are progressive choke - that is, at normal throttle openings only one choke (the smaller one) is in use. The second choke opens only when the throttle is opened
wide. I believe this style of Weber was developed to give cars the economy of a single choke carb under normal driving conditions, with the ability to greatly increase mixture flow to the engine when additional power was needed. As such, I would think that
it would be difficult to synchronize a pair of them. But, as I said up front, I know very little about Weber carbs...<br>
