There is a lot more info availa= ble in rotary engine related discussions on the internet.

Subject: [FlyRotary] Premix vs OMP

I now have 2= engine cores. One is set up for premix and one is set up for OMP.=C2=A0 (I= of course just purchased a set of SS braided OMP lines before acquiring th= is 2nd engine)

My search of the listserv (2006-2010 results) shows that overall pre= mix yields a better distribution=C2=A0(at least for the RX-7 engines with 2= OMP lines).=C2=A0

Is the general consensus=C2=A0still that premix is a better distribu= tion? Still recommending .7oz to 1 US Gal?

Thanks,
Mark
