With only 67 hrs on mower engine has started to spit and pop. If you shake the mower while running it starts to pop really bad. I am going to take a fuel sample and then pull the carb to look for trash.

Never had to do this on an engine with so few hours on it, relashed valves- exhaust valves were out of adjustment. Runs great now.
