Mark Shaw Posted July 30, 2019 Share Posted July 30, 2019 Max, You are looking for a compression release. You can easily make one by installing a small valve in the cylinder head with a rod that extends to a convenient place near the hand crank. I am not sure the early REOs had a place to put a valve in the cylinder head, but many early engines did have them. Link to comment Share on other sites More sharing options...
Max vormister Posted July 30, 2019 Author Share Posted July 30, 2019 Can you send me a photo of a compression release valve maxv1@optusnet.com.au Link to comment Share on other sites More sharing options...
Mark Shaw Posted August 1, 2019 Share Posted August 1, 2019 This is a Model F 2 cylinder Buick with the horizontally opposed engine mounted below the body. The bent rod extension is conveniently mounted near the hand crank (directly above the end of the spring) to open and close the compression release. The valve is located on a nipple at the bottom to drain excess oil to prevent hydraulic pressure from breaking the jug as well as releasing pressure for cranking.
