When you have a S51, your carb ( 16N3)on the picture is not the right carb.
The right carburetor for s51 is the 16N1-11

I cant see the pictures anymore, but the 16N3-1 can also be used for the S51.

Wasn't the best carburetor, it needed an in mechanical perfect conditioned engine.
It was very sensitive for every change in the system.
Be sure that your carburetor is really clean and check your gasket to the cylinder.
Replace the shaft seals if needed, they're often out of lifetime after 30 years.
