Well, start from the fundamentals. Air, fuel, Spark. Spark(ignition), we can assume it's good because you can turn the thing on. Air, well, it's gotta be there or you'd never actually get power. Finally, fuel. How's your fuel pump doing? Fuel filter? Fuel injectors? Check your spark plugs and see what color they are. Check this page to get a DECENT way to read your plugs.
Hope this helps!
