cleaning old fuel out of carbies

**phoenixbeemer** · #1 8 Jan 2009

Hi there. I'm resurrecting my '86 BMWR80G/S and unfortunately I stupidly left some fuel in the tank. So now I have a rusty tank and carbies. Ive disassembled the carbies and need to remove the lacquer like substance all over the carbie parts. Any ideas what to soak them in? As for the tank I've seen some commercial preps from the US that removes,neutralises and coats the tank.
Many thanks.

"Seafoam," much-beloved by KLR enthusiasts, seems to work miracles on fuel system lacquer deposits. I use it as preventative and curative per need. Don't know if its available, or under what name, outside of North America.

Hope that helps.

If you want to clean carbies both externally and internally, just dump them without dissasembly into a container of paint thinners. Works well and is cheap, however it can affect rubber or plastic parts, but you're going to replace them anyway, aren't you? Otherwise, dissasemble first.
