Just got this motor. It idles only, can't get it to sustain an

Blocked main jet?

strip and clean the carb, or simply get a new one.

Haven;t really looked at mine a lot, but IIRC there is simply a
centrifugal governor that closes the throttle when it over revs..

Take off the air filter and see what's what. They are simple beasts.
