Anyone have a dual carb set up for a Mac 72hp?

Not a Mac expert,
As I recall the 72 has 1 carb and the 90 has 2 carbs .

I understand the same as well. I also understand by installing the dual carb set up will greatly improve the overall performance and reduce the running temp of the engine.
Please share your thoughts and comments. To say I'm a novice in the Bensen world would be an overstatement.

I don't know much about the Mac, but there are differences other than the second carb. I believe the two versions also have different ports.
