* What are the specific symptoms of the rough running? Is it sputtering, misfiring, idling poorly, or something else?
* When did the problem start? Did it happen suddenly, or gradually?
* Have you done any recent maintenance? Have you changed the spark plugs, air filter, or fuel filter recently?
* Have you checked the engine oil level?
* What type of fuel are you using?
* Is there any smoke coming from the exhaust?
Once I have a better understanding of the problem, I can offer more specific advice.
