He said he would do some research and get back to me. He did not know why both cylinders would have no compression. Asked if it could be a broken timing belt he said he did not believe it had one. I found some web sites that talked about an ACR system but if I understand it correctly, if the spring fails the release faults to maximum compression rather than reducing the compression until it starts. You really can't see down the cylinders with plugs out, Bud suggested putting a plastic straw in the cylinders and see if it goes up and down when the engine is cranked. I will try that tomorrow and also will also try squirting some oil in a cylinder to see if the pressure goes up.
Can't find manual on that model but some had a automatic compression release that were made to work with a spring and/or exhaust gear. Have you tried calling Kohler?
