Cheers Graham. The passed couple of months I’ve been using the Sandcast as my go-to reference for the K2 rebuild (when in doubt), but alas that doesn’t have the pulley wheel. And tbh, I didn’t give it a thought…So dang when you pointed out the gold passivate finish! (& thanks). Fixed now… And yep, the acid wash… basically 30 secs in a weak solution followed by a distilled water rinse - ie not concerned wrt hydrogen embrittlement (which is fully covered in the plating manual)
If you unearth it then it won't work I'll get me coat.
Actually I may have it the wrong way round. IIRC the drill bit goes into the engine side as that the gap the carbs need to idle properly. The idea being that they are all the same gap when you fit them and you then adjust the idle speed correctly using the large screw on the linkage bar. In the bottom pic it's the left hand carb which is orientated correctly for the drill bit.
