It would help to know the capabilities of your transmitter. EPA/Travel Adjust? Throttle curve? But generally I find it best to set the servo(using the transmitter hopefully) to mid-travel or neutral. Then connect mechanically to the throttle arm of the engine so that the carb is half open. Then using EPA/Travel Adjust set the high and low throttle position. Then if you have throttle curve, run the engine and set throttle curve to give the desired engine speeds at various throttle stick positions.

what I do is move the servo to what will be idle.....close the throttle trim all the way down...then open it up about 3 or 4 clicks......now close the carb.....adjust the pushrod to fit between the hole in the carb arm and the servo arm by sight...now hook up the pushrod.....this shoud give you a closed carb with 3 or 4 clicks of trim left just to be sure....now..open throttle trim so that you have a small opening in the carb throat..... with the throttle stick on the transmitter make sure you are full open...I adjust with my radio if required...... make sure that the carb closes with stick down, to idle, and that you can close the carb completely with trim...

I pretty much do it the same way as the Bus Driver. It's a good way to get 100 or more % out of your servo. I make sure my trim is set on my TX at nutral before I start so i have some trim both up and down.
