Jerry Works put out a two page article in the GMCMI magazine this month. The print isn't large. Extremely well written. And gives an outline on why these new fuels don't atomize well when delivered to our engines by way of a carburetor. These newer fuels are blended to be delivered by way of EFI systems. This new magazine is an outstanding publication. So if your not a member of GMCMI. Your missing some great info. Bob Dunahugh
