I would go with 24:1 for the first gallon or two. After that 50:1 should
work (assuming that the engine has needle bearings for the rods rather
than bronze bushings).
BTW, how did you clean the carbs? As I recall, that engine only had one
carb. And did you mean that you freed up the seized pistons rather than
the head?
Good luck and good boating,
Jim
