OS 160 muffler pressure

[Fletcher, Richard]

Hi Karl, 

    That is what I am thinking of trying also. How large is the main tank?
Also, do you peak the engine before take off or set it slightly rich? Do you
tach it or just get a feel after a few flights?



Thanks, Rich

Rich,

That's the way I run my O.S.160FX. Pressure from the high point of the pipe
into the main tank, which is located just in front of the wing tube. From
the main tank into a small (2 to 4 oz.s) hopper or header tank right behind
the firewall. No pump or regulator needed. Unlimited vertical (and I mean
unlimited) and no sagging of the engine.
