Thanks for all the discussion and as always this brings a lot of opinions into play and with the removal of lead and addition of ethenol to our gas has certainly been detrimental to our old tractors. As summerized from comments of others by CNKS it appears todays 93 octane is not the same as the old 93 octane of the era when my 656 was produced in 1967 but something even higher in octane rating. There is a service station in town (that's correct not a quick mart type store that also sells fuel) that has 91 octane un-blended preminum gasoline without any type of alcohol available. I believe that might just be my best available choice. Maybe I need to get a truck bed fuel tank with a hand pump to bring it out to the farm for the 656 along with a good lead substitute if there is such a thing available. Thanks for all the discussion and your comments relative to this matter, Hal.
