Re: Problems with modern gas

You've got an interesting problem. Actually today's gasoline is much more highly refined than gasoline of the past, though it does have a much shorter static life. How long has that gas been in your tank? If more than 4 or 5 months, I'd suggest starting by discarding it, cleaning the tank and all lines etc., and trying again with fresh gasoline. Has your tank ever been "cleaned"? I assume your pump rebuilds were with materials compatible with ethanol-containing gasoline? Aside from that age issue, gum formation and the other problems you've experienced I've not heard any hobbyists attributing to modern gasoline.
