I recently cleaned and "kitted" all 3 carbs w/no notable difficulties.
When I started it up, it idled very nice for about 15 seconds and then started sputtering. I noticed fuel dribbling out of the larger of two holes on top of the carbs. Did I miss something getting plugged inside?
FYI, I just ordered the OEM service manual. Should be here by the end of this week.
Went back thru the carb kits and discovered a tiny little rubber stopper. Installs on the bottom end of the main needle valve and maintains the proper adjustment for valve seating. Started right up w/no observable problems.
Now, I've gotta put new seals in the lower unit.
