Re: Carborator adjustment V-4 johnson
RCpilot... Loosen the carb roller set screw (if needed) so that you can back the roller away from the cam.<br /><br />Adjust the throttle linkage rod between the upper and lower carburetor so that both plates are closed at idle, and they both start to open at the same time.<br /><br />Adjust the carb roller so that the throttle butterflies start to open when the scribe mark on the cam aligns with the center of the carb roller. That's it.
