Apparently there is one that can use the 1.21,, but I'm gonna stay out of that situation.

Number = CFM
.98 = 190
1.01 = 240
1.02 = 245
1.08 = 287
1.14 = 300
1.21 = 351
1.23 = 356
1.33 = 424

Found this online after wondering how much difference was in the two carbs. Don Jackson

would that be Gary Summers current U/SA record holder-I had heard he was running the 1.21 carb?
