2 holes on the side of the bowl screw (they passed through each other), and one in the top of the screw that went down to the passage of the other 2 holes. 3 holes total. Is this correct?
Yes, this should be correct. Make sure ALL of the holes are fully open by spraying through them with carb cleaner spray. Even a small restriction can affect the mixture and cause the fuel mixture to be too lean or too rich.
Keep in mind that the smaller the engine, the less fuel it needs. Some of the passages can get REALLY SMALL!!
