Simplicity conquest 22hp B/S issue

[billwhitbeck]

My mower is running rough, it starts out good, but after 30-40 mins runs rougher, particularly after putting it in reverse. I have put new fuel in. Seems like an electronic issue? Spark plug? Any ideas appreciated.

Check air filters, fuel filter, then spark plugs, replace all if necessary.

Thanks Mark. I checked all these. New plugs, cleaned air filter. It seems the oil was overfilled, wont start now. next steps?
