I have a 2 year old JD lawn mower with engine problems. Runs rough and
hard to start. Any adjustments that I can make? Air filter and spark
plug new. Gas is also new.

Ignition, fuel, air are it...beyond that you're talking mechanical
damage. Eliminate problem(s) in each of the above.

Which engine, which mower? 2-yr isn't long unless it's been shorted on
the maintenance or somehow abused. Older and I'd suspect the
traditional carb-to-body connection loose that screws up air mixture by
extra air inlet which also has variable symptom as runs owing to the
vibration changing the gap. Shouldn't be a problem w/ newer but never
hurts to check.

If no joy, there's always Mr Deere to help...
