Default RE: Perry pump on O.S 1.08??????


ORIGINAL: raimondi

Hello everyone, has anybody used a perry pump on an O.S 1.08? and if yes could yuo tell me how it works, and give me the tips on it. I´m planing on using one on mine so I can place the fuel tank back on the C.G of my plane. Thanks much!

You will find the the carb on the OS108 will not allow you to adjust the low speed low enough to get it real clean unless you bleed off some pump pressure by running a bypass. I also removed my restrictior sleeve as it is not needed with a pump. See this thread for details.

With a pump my OS108 spools instantaneously. Click here for wave file of it spooling with a 16 x6 prop. http://home.comcast.net/~ccrsfield/108FSR16x6zing.wav
