Catch me if you can
Aside from the likely exhaust leak mentioned by so many, the number one cause of popping on a single cylinder engine or “popcorn” on a multi cylinder engine is lean jetting, but not the main jet. It’s the pilot jet and air or fuel screw. Odds are on a stock setup the pilot is not so far off that it would cause this UNLESS it is plugged a little which is where I’m putting my bet in this case. If it is the screw then you have to determine if it is an air screw or a fuel screw. Air screws are located on the carburetor before the main jet (USUALY FOUND ON 2 STROKES) and fuel screws are located past the main jet nearer to the engine (USUALY FOUND ON FOUR STROKES). If it is an air screw you turn it in to richen the engine. If it is a fuel screw you turn it out. If at any time you find that the engine runs best with either screw opened more than 2.5 turns, or less than ˝ a turn it is a sign that the pilot jet should be changed to the next size which corresponds with the problem. After checking the exhaust for leaks I’d open the carb, remove and clean the pilot jet, check that all the jets are stock and that the needle clip is set in the middle, or stock position and set the screw at 1.5 turns and try it.
