I have to agree with that, I thought I had the one in my truck (71 Chev) cleaned out pretty good....Nope! When I did get it to stay running after a bunch of additives and fresh gas, My exhaust smelled like varnish for about a week.
I finally found another tank from a friend and swapped it out, problem solved and lesson learned, that was a PITA.
