YS91AC help

I picked up a used YS91AC and a one way valve. How do I hook this thing up. I can get it to idle but high speed is a joke. I must be doing something wrong. Any help would be appreciated. Thanks in advance.

YS91AC help

You have the check in backwards most likely. The engine sucks fuel like any other engine at low rpm but once you try to rev it up it needs the tank pressure, which if the check is in backwards you wont get. If hooked up right you should be able to blow through it towards the tank, but not the other way. Also go to

www.ysperformance.com

They have the instruction manual first page there which shows you how to hook it up.
