Ho ho ho!
Does anyone know where there is quality information on amal type 6, 76 or 276 carburettors positioned with the mixing chamber horizontal and “special” float chamber to suit? I understand that several pre war bikes had carb’s fitted in this orientation including single cylinder machines. Can someone tell me which bikes they were?
I suspect that the front carb on my twin (horizontal fitment) is not operating correctly on tickover It strikes me that the carb will struggle to perform satisfactorily at low rpm i.e tickover but as these were fitted to singles they must have worked satisfactorily? It also strikes me that fuel level is absolutely critical; above main jet invert level (as it is horizontal) causes immediate flooding, a little lower impedes the ability of the carb to draw fuel. The carb body can be rotated about the inlet stub to lower the main but the extent is limited as this causes the float chamber to tilt of its axis with inevitable flooding consequences. This cannot be a new problem surely?
