    The OA series motors IMHO are some of the best that Johnson produced.
    I have an OA55 that is my go to motor for a reliable ride.
    Starts at 3/4 needle open and runs at just better than 1/2 open.
    Easy starter when cold or hot.
    If yours doesn’t start well and run well you may want to go through the ignition and fuel system.
    I also have a 1933 OA65 that is just as good a runner.
    Great motor and a great find.
