a combination of volatile and evil smelling fluids found in the dark recesses of the shed seems to have done the trick. Jet block out and all seems to be clear now. Bike even started!!
I think that was in the mix...nitro...something-or-other, according to the German label it's a universal solvent. Splashed a bit of acetone and brake cleaner around for good measure and make sure my lungs got a good clean out as well. :grimacing:
