You know. With a single plane and the RPM you're pulling. I'm wondering if an 850 carb or bigger wouldn't net you another 5-7 horse. Maybe even 10. Did you guys try any other carbs?
I just tried the 750 AED I already had, it just need one bump in jet size on the primary.....I'm building another engine right away so there was no chance in hell that I was going to even think about a different carb.....Mike who put the engine together tried for 2 months to get me buy a real modern cam for it and I refused!
