[AT] Another Question...

    Ben;
    If you are referring to this action with the engine not running, it is 
normal. With the engine running the governor always wants to return the 
throttle to the idle position. The spring actuated by the hand throttle is 
what controls the engine speed. Pulling the thottle for more speed increases 
the force on the spring and makes the governor work harder to slow the 
speed. At each throttle setting an equilibrium is established between the 
spring and governor to give a constant speed. Under a load the engine slows 
down and the throttle spring overcomes the governor and allows the 
carburetor to open attempting to raise the engine speed and as the engine 
speeds up, the governor again overcomes the spring and reduces the power.

    Hope this is clear..

                                Gene
