The regulator(? suppose that's what it is), worked ok, while there is no load on the motor, it clicks away, and a hand on the rim of the flywheel, and it stops clicking, and the motor gives full power. Could not see any number on it, and the 1/3 hp is on the little notice that came with it from Austrailia. There is no ash pan, so there was a nice round burnt area of grass underneath the fire box at the end of the day. Ian S C
