I dont have a wide enough shot to show how the throttle link works.
If you put the parts diagram together in your head that will give an idea. Keeping in mind what I said about about only 3 detents.
There is a lever on the side under the air cleaner housing (item 16). Perhaps it should just be that lever and no cable.
The drag of a cable makes it impossible to feel the detent for full speed. Perhaps there is meant to be no cable.
I would need to find an old HR21 fitted with the GV150 originally to find out what cable if any they had originally.
It definately does have a keeper for the outer of a cable.
Perhaps it should have a cable similar to the GXV motors. Rather than the solid core spiral wound cables most mowers use.
I am not sure how hard it has to push to get the motor to shut off.
I was not running the engine while adjusting. I was adjusting and then running like you suggested.
It runs the same filter as the GXV120. The housing is different due to the manfiold going 45 deg and the carb being beside the engine. The GXV120 has a 90 deg in the front, this has a 180 deg at the rear.
