OK, on the side of the powerhead is a vertical throttle shaft. The bottom end of that shaft slides into a slot on the bevel gear that moves it. That bevel gear has a pin on the bottom that goes into a nylon bushing in the steering bracket. It is common for corrosion to build up around that nylon bushing, causing it to squeeze tightly on the bevel gear pin. That’s why I said to wiggle it to see if it is too tight. Solution is to take it apart and clean the corrosion out and re-lube.
Another common problem area is where the shaft rotates in the tiller handle. But you said you took it apart and cleaned it up.
The gears were significantly changed mid-year 1956. The new style will fit your ’55 and are a vast improvement. Gears are sold as gear and shaft assembly, and you have to change both g/shaft assys if you decide to update it. They are kind of $$ unless you find some used ones.
