Thanks guys for the input!
I am using an old ZW.

Hi Guys,
I am new here, but maybe some can recognize me from others forums.
I bought my first 773 Williams engine, wonderful engine. My only concern is how can I reduce the speed start. The diagram show and voltage board, is this for the motor?
thanks a lot
Andre.
