TR4A carburettor overhaul

I took the carbs off the Tr4A today as I was having trouble adjusting the carbs to achieve the correct mixture across the whole rev range. Once off the car there was obvious play in the butterfly spindles. This would lead to a weak mixture at higher revs. The floats were also set to high at about 10mm gap between float and top edge of cover and there was a lot of debris in the bottom of the float chamber. One good point is the pistons and damper assembly's look in good condition and the Piston lifting pins are both free. The photos below show the general condition of the carbs.
