Power Steering Servo Replacement Issue

Once again looking for advice for a rookie. A few days after my first race I noticed my servo was leaking a little fluid (Woodward remote servo). I had another unknown used servo on my shelf so I just switched them out. Did the swap and checked to make sure all lines were going the correct way. Turned the wheel from left to right on the stands with the engine off and all seems normal (no binds). Started the engine with the car on the ground and while turning the wheel to the right, all seems normal. When turning the wheel to the left, power steering is nonexistent. Is there something I’m overlooking while replacing this? Thank you in advance!

Educated guess...Likely a bad servo....maybe why it was on shelf? Other possibilities: http://www.woodwardsteering.com/PDF/...leshooting.pdf http://www.woodwardsteering.com/Detailed-tech-info.html

Thanks! I'll work through the detailed troubleshooting guide and see if anything will work. I'll just plan to have my old servo rebuilt just in case. Thanks again!
