There is a good thread "Bing 45 on the Mac" in the engine threads which should answer a lot of your questions.

Ben, The best carb for the Mac is the Holley 1940.The model 1920 will work but is more prone to fail because of vibration to the float.

Youcan use the 1940 just remember that when you trailed your gyro keep fuel in the carb. Bensen recomendation was to run the engine dry so you dont have fuel for an extended period in the carb. This to prevent the deposits and any sludge due to a long storage period. But if you fly every weekend this is not an issue.

Now as CFM 1920 have more fuel flow vs the 1940. But I like the double float safety features.
