I had a carb set up by Bo Laws for gas, Q16 and C45. They did an interesting trick where they installed what they called an "upper jet". Basically they made the inlet to the booster a jet since it becomes a restriction when you are flowing a lot of fuel. So when I would switch from gas to Q16 or C45 I had to change the main jets, the intermediate jet and the upper jet. Once I changed everything over the carb was capable of flowing a lot more fuel. It will be interesting to see what Book does with your carb.
