Run it long enough to make sure it runs OK. Maybe you can get the needles set and get famiiar with the engine.
Talk about getting Grumpy.My engine test stand is the old Road Runner airplane that is 31 years old.I run the engine for maybe 10 mint's to adjust the carb then put it in the air.
Did not get to fly the Syssa today was too cold and windy,no snow though.
BC Grumpy no two.
