Like the carburetor, the petrol tank had a layer of brown rust\sediment that i could seen - i did not take a pic - but as a reminder the carb is pictured below:
I have filled the tank with caustic soda (100g) and cold water - will check over 48 hours on the results.
A few minor jobs left - and hopefully booked for a MOT before Sept end.
24 hours later..
Will leave for another 24 hours..these were the deposit removals..
