so the mower will not start and I tried all the usual things to get it running with no luck. I suspect that the carburetor is not opening up due to this push pin behind it. I assume its to keep it in time with the engine, although im not confident its the main problem, however I am very curious about how it works. when I spin the flywheel, the rockers move in sequence and yet the carburetor push pin does not move. any idea how to diagnose push pin?
