Subject: [FlyRotary] P= remix 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 this 2nd engine)
My search of the li= stserv (2006-2010 results) shows that overall premix yields a better distri= bution=C2=A0(at least for the RX-7 engines with 2 OMP lines).=C2=A0
Is the general cons= ensus=C2=A0still that premix is a better distribution? Still recommending .= 7oz to 1 US Gal?

Thanks,
Mar= k
