Engine Honda HRR2169VKA

Just been given this HRR2169VKA that wont run above idle speed, cleaned the tank and filter, checked all lines, cleaned carby (removed main jet/checked all galleries ) put new fresh gas, still will only idle -running rich, noted the governor arm cannot be moved in either direction so thinking either stuck up? or some one has moved the lever on the governor arm?

Would it be possible the governor has seized up inside the engine? -told this is a newer model -auto choke and auto throttle run for 1 season only

Thx Steve
