I was thinking, since one side of the carb feeds 1 valve, and the other side of the carb feeds 2 valves wouldn't it be more effitient if there was a bigger gap in the jetting? Maybe not so extreme as something like 200 in one and 150 in the other, but something like that. I would think the fuel would be mixed better if it was gapped more. Just a thought, I don't know if anyone has tinkered with this yet. I think I may try over the summer.

 

The two carbs actually feed all 3 valves. Not one carb one valve, and onother carb two valves.
