Is there a chance that your gas there is a similar formula to what we get in the USA?? if so at 8 months old, or more, old less volitele gas plus the addition of a contaminant (the sillycone) would sure interfere with starting. 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. I know this because when the smoke comes out, it stops working. -------------- Original message from "Narve Nordanger" <narve.n@xxxxxxx>: -------------- > Hello group, > > Those of you with excellent memory might recall my frustration from last > year when I had problems starting my C-300 at all, asking whether anyone had > any advice.
