New member here and looking for help.
At 200 hours the check belt light came on. Removed the converter cover checked the belt and followed instructions for the reset. Now I have a miss that starts at 35 mph and it won't go past 50. It acts like you are turning the key off and back on. Pretty well ruled out carburation and fuel flow.
When I had the cover off I started the machine and noticed later a warning not to do that.
