Hmmm yeah not sure, these (the pump rod settings) will be crucial in getting the engine to run right, I don't want to send the carbs having been freshly rebuilt and then find that they aren't running right only because the accel pump settings were out.

Hey Deano, no email yet.

I ran the pump rods at only about 1mm lift (maybe less) on my last Mikuni carburetors, and that was running on a fairly heavily worked A12, perhaps these are the same.

Surprisingly dellorto's offer a combination of the Weber and Mikuni format, which in my opinion makes them the best carburetor of the lot. I'd need to see how easy they are to set up before I made my mind up but at the moment all the things I liked about Weber and Mikuni are featured all in the dellorto carb. Interesting stuff.
