I just got it at an estate sale saturday.I have no clue.Its a nice looking motor.I have the foot off changing the impeller.I pressurized it and it held 12lbs for 30 minutes .The foot grease had no oil in it.The fuel lines were hard and I do not imagine it has run in a very long time.I poured atf in it right to start with and let it sit for one day.Compression is 112 on both cylinders and I have spark although I don't know if it's enough.The jet I was referring to is the top one .High and low are on the bottom .It might be air I'm not sure.I think this motor will run but I'm sure it probably needs carb cleaned at least
That's why I need the settings
