[TR] weber carbs

[Michael Marr]

Apparently, they put this exact set-up on Nissan 240, 260, and 280Zs, too.

Wouldn’t DCOEs be more efficient, from an airflow viewpoint, in that they are horizontal, vs the downdraft DGV?

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.

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...

I think I found the ID – could it be a 32-36 DGV?



Yep.
