On the 1983 115 Tower of Power Merc, just finished the carb rebuild. It ain't no wonder it wasn't running right. The Seloc manual does not suggest a starting point for the carb adjustment. Before I have always started 1 1/4 turns out from a light seated needle. Open to any advice. By tomorrow morning the new tach will be installed along with new fuel tanks, lines, bulb, water separator/filter. I do have a test tank that I can run the engine in if that's any help.
