After installing the two carbs install started the engine ... it started but maxed out rpm's. I checked installation, carbs were installed properly. But, on the top carb, the linkage that moves the butterfly is not connenected to anything. I looked everywhere but the is no indication of a link. Where can I get a manual or a youtube video showing how to COMPLETELY connect the carbs. There .Just be some sort of linkage that moves the linkage from the throttle. Does anyone have any ideas?
