That little spacer between the cam cog

and the dizzy drive cog. Google results show it both ways around. Does anyone know if the side with the larger swelled out bit goes fore or aft.
 
If you mean the fuel pump cam, IIRC it's marked so you get it the correct way around, but if you did fit it incorrectly it won't line up with the fuel pump lever.
 
Well, I have 4 of them , each stamped with 2 F's, which I have to guess is front, however, if fitted that way, the fuel pump lever looks like it will half bridge the missing piece if the fuel cam, for some of its rotation.
