WALKERS210-RCU

I picked up a 120 today and do not have the manual for the engine. On the back of the pump the previous owner put a small lenght of fuel line over two of the fuel input/output. I need to know which one is the intake for fuel and does the second one go back to the tank or just plug off??

If you send a email to us at the address below, we can send the instructions. Let us know if your pump has a brass screw in the center. That determines which version of engine you have.

Thanks for your assisatnce, by the E-Manuals it appears that I have the Surpass II and prior to getting the manual I did a little deductive reasoning and had the plumbing worked out. The engine will start perfectly and idles super, top end is great and I got to maiden my plane this weekend and must say this engine is great. Only thing I need to know now is about setting the low end, in the manuals there is no reference to setting lowend and if you come back to a low speed for extended time in flight it seems to load up slightly, not enough to worry about but would like to know if it can be tweaked out.
Thanks

With an APC 15 x 8 prop, we normally get the low-to-mid-9,000's on the O.S. FS-120 Surpass engines. A 15 x 6 would be a bit small, and turn more RPM.
