I am renovating a used and abused bed redefiner that came with a GX240. The entire machine, including the engine, was filthy. It had an oil leak at the bottom of the crankcase. I had to take the engine off anyway to do some welding on the frame, and decided to clean the carb while I was waiting for gaskets. The engine would start with a pull rope easily before I worked on it. NOW it won't start at all and in fact won't even pop with starter fluid. It feels normal when pulling, no noise, decent compression. I put an inline spark plug tester on it and showed a spark.
While changing the crankcase gasket out I ended up pulling the counterweight gear and shaft out, as well as the camshaft gear and shaft. I needed to do this to be able to fully clean the sump. I was very careful replacing these re. indexing the marks on both gears. I also took the valve poppets out and cleaned them and made sure they went back in the holes they came out of.
I'd appreciate any suggestions. I am thinking it is not anything to do with the oil safety switch since it does show a spark if the ignition switch is on. I feel like even if I had messed up the carb it seems like it would still at least pop with starter fluid. I do have a compression tester and will hook it up tomorrow; I am not sure what I should be reading since it does have a compression release. I guess it's also possible that the spark tester is showing a spark but I didn't actually test the plug by grounding it. Any ideas? Could something have moved in the valves that would cause this? I haven't had the valve cover off yet but will do that tomorrow also.
TIA!
