MG Midget and Sprite Technical - 1275 carb question

Hi Having problems with my midget with very lumping running, missing and no power. First went through the full ignition system with no improvement. So I then wondered about the carbs. Checking the float chamber there was some rubbish at the bottom which I cleaned out. I then went on to strip the carbs removing the top housing and wa surprised to find 2 springs together on top of the needle assembly. Is this normal or should I take one out?

There should only be one. I would get two new springs (one for each carb) and replace them both then tune the carbs.

With engine running spray WD 40 around all the joints. Should the engine speed increase as you spray it, it would indicate a leak. The main are of concern is around the inlet manifold face to the engine, or at the butterfly spindle on the carb.
