Hi Flatlinerz,
Remove fuel line from carby and Drain the tank into a container, then Remove it.
Throw in a small amount of turps to breakup the gunk. Give it a good shake.
Drain and flush With Water.
Hot water flush with detergent(again giving it a good shake) then drain and finish with a hot water rinse.
Blow out to dry or mop up excess water with a clean rag.
Remove tap and flush through. Blow out tap and filter then check seals if applicable.
Refit tap or replace.
Refit tank and fill, checking for leaks.
Clean cap the same way and blow out.
Conpressed air only to dry. NEVER NAKED FLAME.
Good luck. ...
