I had an early postwar Scott single with a cast tank and side covers. Tank was about a third full of solid remains of fuel  Removed tank, plugged fuel outlet, poured in ladquer thinner, replaced cap and set out in sun. After a week, poured out a jelly like substance and excess lacquer thinner. Poured the lacquer thinner back in tank. Repeated several times until tank yielded no more jelly.

A member of GLC converted an old wringer washing machine to slowly turn a tank so nuts  and cleaning solution could work on deposits without manual effort.

I have split and resealed a number of Mercury 2 piece cast aluminum tanks. Practice may not make perfect, but, it will improve your technique. It is    I ASSUMME that other brands may also be split and resealed.

If carb and tak have had issues, it is possible fuel filer, shutoff and fuel line may need attention.
