I'll post on it in the next couple of days; been just buried in other stuff recently. We had some issues with the engine at first, but figured it out, and the engine went on to make good power. We did try both carb combos, but the first carbs (the 600s) had relatively poor results because of another problem that we didn't discover until after we switched on the 780s. So unfortunately there wasn't really any good back to back data on the two sets of carbs.
