Misfire

[350TSS]

In your position I would give the tank one more concerted try with a hose/jet wash and some detergent and after about 4 thorough rinse outs I would dry the innards out with a hair drier in the filler opening (moving its position several times so you do not blister the paint). If the problem still persists then I would bin the tank.
Such issues can be very frustrating and demoralising - I wish you luck with whatever you decide

Thank you.
Yes extremely frustrating and expensive due to the debris entering the carbs and quite possibly being indirectly responsible for the misfire which in turn led to the crank problems...
I have already been advised to bin the tank which I paid good money for-just goes to show how careful you have to be.
I think the only way this tank could be used is by the application of a liner but I know there are big problems with these now due to the composition of modern fuel.
The old tank has gone to a specialist for gas welding and will then need to be re-sprayed.
