When I have the throttle WO, should the butterfly in my carbs also be WO? I can physically open the carbs a bit more at WOT by manually pulling the carbs open. Overall she runs pretty good. I don't have a tach, will have one next week to check for proper RPM. My manual (Seloc) really doesn't cover cable adjustment very well, so I thought I'd see if anyone here knew the answer to that?<br /><br />92 Yamaha pro 50 is the motor.<br /><br />I've tried adjusting the throttle cable to allow for the carbs to open up even more, but I can't adjust it to the point that will allow for it to open those butterfly's completely. As I advance the throttle, it first advances the timing, then it kicks into open the carbs. The piece of plastic that the carb control sits on advances the carb to a point where it won't go forward any more, but there is a lip on the piece of plastic that would allow for the carb control (basically a roller that advances the carb butterfly's open<br />) to fall down about a half inch and maybe open the carbs all the way. But I can't get the control to do that with any adjustments to the throttle cable.<br /><br />Maybe this is too confusing to describe in words alone...
