I have a murry 20 HP motor will not turn over when the spark plugs are in. But will if they are out. Any recommendations?
@dougtractor, could be a bad starter which will not have enough power to turn the engine over once it is under compression. Depending on your engine, this could also be caused by valves that are out of adjustment. That would cause a compression release to not work and the starter does not have enough power to turn the engine over. A faulty camshaft can also be a cause, so this will all depend on what engine you have
