Small Engines (Lawn Mowers, etc.): Honda GCV160 starting problem, honda gcv160 engine, honda manuals

Question
My MTD mower uses a Honda GCV160 engine. 3 weeks ago it wouldn't start. I would pull the cord and there was no resistance telling me there was no compression. I checked the cam cover and found it dented. I straightened the cam cover, this resolved the compression issue. While troubleshooting I pulled the fuel bowl but didn't find any dirt so I replaced it. The engine started but only ran for about 10 seconds then it stopped. I have replaced the plug but have still had no success. It starts but only runs for a few moments. It will not start a second time unless I let the engine sit for 30 minutes or more. Any ideas would be appreciated. I do not have any illustrations, exploded views or specifications on this engine.

Answer
The dented valve cover throws up a bunch of flags, including a
jumped timing belt.

here is a link to Honda manuals, if it doesn't come up just google the dist name and Honda.

If the dented valve/cam cover had such an impact on the compression
and running, that is likely where you need to explore.
