Hello everyone, I have a 1968 arrow glass 120 stern drive with the CUE-16c engine 153 ci dual 2bbl carbs. The problem is it seems like its idling fast at warm up and doesn't taper but just keeps getting higher and higher rpm then I get nervous and shut it down for fear of over doing it. What is the proper idle idle speed on warm up for these old engines with choke disengaged and should I prime the carbs with the main throttle before start up. Thank you for your time!
