It isn’t yellow paint and for some reason with the LED light ether over exposed bits and changed material colour, its 60 years of crud from evaporated petrol, some places it was on very thick but did blow off a bit. that carb in my infancy I fitted for my father, as originals with the ball floats being dented looking like golf balls often after being left would go back to start it only to find been leaking. Looking back that pump was a real life line as the farms only water supply was the Bore hole that Panks put down in 1942 that regularly was out of action in the driest times so was a great help watering stock from ponds. Original carbs had T 12 and T 13 on with C1266? no JAP script, ordering a new carb I somehow was afraid when asked for butterfly orientation had got it wrong? well if I hadn’t would still have got the blame, luckily that carbs neck was universal moulded and I re-drilled and plugged and he never knew. In those early days my equipment to make anything was gutter bolts, hacksaw, file and Black&Decker drill, that carb number 01433C type 13TCA-2 and the later new correct one I fitted 01392 from just over 20 years ago.
