I was nervous buying the used carbs and Its obvious the linkage has been ground out bringing the secondaries in later which may affect the timing of the accelerator pump shot? the shot is done long before they open which in my mind gives it way too much when i'm cruising or part throttle and nothing when I need it when the secondaries are opening and they replaced the secondary metering plates with 12 sizes larger jetting who knows what else they did??? I'm just ready to start fresh. I didn't really have the money either but I'm ready to get this thing done. Me and the kids will eat RAMEN & Mac'N-Cheese for the next month!
