I searched and can’t find whether this has been discussed before:
‘46 C140 with Lycoming O-235 and MA-3A.
Bought the plane where it was based at 5000’ elevation. Now plane is based at sea level.
Because of increased air pressure the ‘new’ home airport, does the idle mixture adjustment screw (and idle speed screw) on the carb need to be adjusted? It would’ve been last set at the previous 5000’ elevation airport.
