Normally I retype all this info. But there is so many posts about 009s and recently the CSP vs. Crossbar info. Check out the search function at the top of the page.

Really simplified:
1. The 009 doesn't have enough total advance. It's like a bed sheet that's too short. It covers your feet, or it covers your body, but not both at the same time.
2. The crossbar linkage has too many moving parts that can introduce slop, the parts are never manufactured to any sort of tight tolerance, and so even when it's set up as well as possible it's still easy to open one carb and not the other. The ideally perfect linkage would never, ever, ever allow that to happen. The CSP is much closer to that ideal than any of the cross bar linkages.
