Paul, sorry for being late with the answer as I haven't attended the computer for a few days. Being an amateur I of cause have both poured fresh gas and starting fluid into the carbs numerous times (with no apparent result). Actually believe that the Norwegian gas is less volatile than the US variety, as it is less mix of bio-additives here and while we often have to change the gas from fresh (meaning old cars) US-imports, that is rarely needed with the standard stuff in cars already here. Also, paying in excess of $9/US gallon as we do now in Norway one should possibly expect some level of lasting quality?

Have you tried dribbling just a little fresh gas down your primary carburator?? -- Paul Holmgren 2 57 300-C's in Indy Hoosier Corps #L6 CPUs run on smoke.
