xenon172 Posted March 31, 2009 Posted March 31, 2009 This is a photo of an old Clinton engine that has a hinged cooling vane that is linked to the carburetor. It is something I have never seen before and I would like to know how it works, if it works and has anyone seen this type of design on any other brand of engine.
BLT Posted March 31, 2009 Posted March 31, 2009 Briggs used that for years on select smaller CI engines and smaller aluminum vertical shaft WB mower engines.
andrewk Posted March 31, 2009 Posted March 31, 2009 It's an Air Vane governor- Common with a lot of engines these days too- The air moving off of the flywheel forces the air vane to move back, or open the throttle butterfly- There is usually some sort of spring resistance that the vane pulls against, so that you can adjust how hard the vane pulls on the carburetor- The looser it is, the more it'll rev, and vice versa.
Brettw Posted April 1, 2009 Posted April 1, 2009 It is a type of governor. It would need the shroud, amongst other parts at the carburetor to work properly.
