    My wright stander for the past week or so has been acting up. When I choke it and start it up with the throttle down low it barely sounds like it wants to run. It'll putter for a few seconds and then shuts off if I push the throttle up to fast. It took a little cranking to get it started back up again today and when it did it blew out a bunch of black smoke. Any ideas on what could be the problem? Thanks

    Check your sparkplugs and clean your air filter...
    A simple tuneup won't hurt it a bit...

    Bent push rod. My John Deere did the same thing and it was a bent push rod

    Black smoke is improper combustion.

    Like the man said, replace spark plugs (gap .030) and air filter.

    Be sure the starter is disengaging that causes funny sounds and crazy starting. I thought the engine was breaking up.
