My '72 500L has a Dellorto DHLA 40, and it appears that the only way to remove it is by pulling the whole engine out of the engine bay. The yellow circles are studs which are too long- the carb hits the engine bay before it's free of them. The blue circles are nuts to join it to the manifold, with x's being on the other side... several of the blue marks are seemingly impossible to remove without the whole assembly being off of the engine or at least out of the engine bay. Does anyone know how in the world I might be able to remove the carb without pulling the engine?? I can't even access the spark plugs either because the manifold is in the way.
