    I just bought a used 420 off of ebay. The throttle doesn't work and the shut-off switch doesn't work either. Need some help in the repairs. Any help would be appreciated.

    It is not terribly complicated just take the handle apart and look and see what is wrong. Be sure that the throttle cable hasn't slipped out of its yoke on the top of the carb before digging in further. And check wiring on the switch to see that one side is grounded and the other side is connected at the engine before pulling the throttle handle apart. These are really good units so good luck.

    can anyone get me a picture of how the inside of the throttle handle in supposed to look like. On the throttle cable itself. Does the little knob go on the outside of trigger or on the inside?
