Bob,

Here's what it sounds like to me – when you put the control arm back on the carb you didn't get it in the same position it was in previously (I've done the same thing). Here's the easiest way I to reset everything:

- Disconnect the pushrod from both the servo and the carb.

- Reset the throttle settings on your radio back to stock with every electronically centered.

- Move your throttle to the mid-point (½ throttle) position and make sure the arm you put the control rod into on the servo is sitting at the 0 or 90 deg. point.

- Move the throttle barrel to its half-open position, and loosen the barrel control arm.

- Hook up the clevis on the barrel control arm and depending on how you hook the pushrod at the servo end:

- If you have a Z-bend at the servo end, then tighten the throttle barrel control arm making sure the barrel is half-way open. Try to get it in the best position for good movement either direction – you may have to screw the clevis in or out to do this.
- If you us EZ-connectors, position the throttle barrel control arm to what appears to be the best position for your particular setup, tighten the arm down on the barrel, then tighten the EZ-connector on the servo.

- Go into the programming on your radio and start programming the endpoint, ATV, etc.

Hopefully this will work for you – this is the procedure I use for all my engine installations, regardless if it's new to that airframe or I've had the engine off the plane for repair/maintenance work.
