If you have any problems Al I can take it. I'm sure one of the executive could also take it.

Ya Thanks Dave, but I have already read all that but I still don't know the advantage over how it runs now.

Are you running pressure from the muffler to the main fuel tank?

I have run the uniflow system on my TSK with good results. But to give you some background on it. It was designed to provide consistent fuel pressure all the way through the tank on the notorious OS 46 heli engine. Avoiding the dreaded leaning out at the end of the tank. Not really needed on the modern heli engines or the pumped engines. IMO it is a waste of time and added complexity. I feel it has run it's course. If you are having jetting problem's still, there is a wealth of info for the OS91 out there. Just do a search. It is recommended that you have .012 shims (.008+.004) in it as it will give you a broader range for tuning.
Call me if you need help.
PS: start at baseline settings (rich) and adjust from there
