Am new tonight but noticed several questions re Clinton motors. I have no connection to but am aware of Clinton Engines Products Company on Maple Street in Maquoketa, Iowa - ph 563-652-2411 - where I am currently working on a project. The company is the vestige of Clinton Engines Corp and has parts, kits, manuals, and a lot of knowledge about these motors. Might be a source of good help on these motors.
