Hi Robert, I replaced the pan gasket on my HRM 215 sxa mower and now the governor doesn't work.I can manually adjust the rpm by moving the governor actuator, but the actuator doesn't seem to do anything by itself. I saw your response of July 20, 2012 for similar problem, and would appreciate if you could show how to recalibrate the governor, if that might be the problem. Was there a procedure I missed? Thanks!!
