I figured it out, and I have to wonder how this will or has affected the test runs and nature of the bike.
Here is what was happening. On the throttle like the secondary link exists behind the primary throttle link. There are springs that are supposed to be set on the "hip" of the rod where the parts are to be exactly placed. This coils for the spring behind the assembly right next to the carb, and the spring that sits between the secondary lever and the primary lever. One coil was in the joint between the secondary and primary throttle arms causing the secondary to hang when operating the throttle, So the secondary and the primary were "running together" at low speeds, or when only the primary is supposed to run the show. Both butterfly are opening and the system was being drowned in mixture. When the throttle reaches cammed portion of the accelerator pump arm and the cam for the secondary arm itself. The throttle would hit that spot, and the secondary butterfly would snap shut, and re-open indepently and complete the action at full throttle. In other words through the range of the throttle, the secondary butterfly would snap shut after opening with the primary until it hots the spot where the secondary is supposed to kicn, and re-open again.
Yea, and if I take it easy, no snap and the bike runs great. So I found a coil stuck down in the area of the return springs. Its first coil was being smashed against the primary arm, causing it to open when it was not supposed to. I loosened the bolt, took a jewelers screwdriver and walked the coil out of the area where it was stuck until the entire coil was sitting on the "hip" of the cammed area of the throttle bar. Next I was able too carefully apply roughly 10 to 15 pounds of torque, than locked the nut in place with the special washer....no more snap of the secondary, and this cures the rich low RPM running, hands down. I am off for a test drive when it cools down. And it fixed the issue, I opened the carb 50 times on the bench with no snapping back whatsoever.
