180 Servo Mod

Ok, I installed two 1/4 watt 2.2k OHM resistors on a Hobbico CS 80 servo as published on the WEB. Repostion resistor twice. Still only getting 90 degrees of throw. Any chance I need to go on top fiddle gears to free up? Any Ideas?

Thanks

I figured it out LOL. It was the transmitter (old Ace Nautical Gold) it needed to be setup for full throw hehehe.
