Also check your wires. This engine has a Fuel cut off solenoid attached to the Carb under the air filter. If your battery connections have corrosion the wire will not get juice all the time and the solenoid will cut off intermitantly.
Oil level also controls this solenoid. Replace the fuel filter. You don't have to buy a Honda filter one from the auto parts store will work fine. Also try running the engine without the air filter for a min to see if that is the problem. If it runs fine without the Air filter then you found the problem.
