    Any you guys got suggestions on how one would control the throttle on a small gas engine ? or recommend a small dc accuator arm with about 6 inches of arm?

    one like this one ,, but WAY cheaper??

    Can you could define the problem a bit better?

    Why would you need that much travel? Small gas engines usually have very little travel to their throttles, and the normal method of control is to rotate a shaft that has a butterfly in the venturi; less than 90° of rotation.

    There is also the matter of a governor, to prevent engine overspeed under light- or no-load conditions.

    Yes it is a 10 hp side shaft motor.this motor is on a bandsawmill. that I would like to use the existing throttle lever ,mount a pivot, and find a dc arm I can control it with,, without taking any of the engine our carb parts off.. looks like 4 inches would work,, ??

    Well, you might look at these:

    Not cheap, but about half the price of what you were looking at.

    You'll still need limit switches and relays to stop the travel of the actuator, or you'll bend/break something.
