Right i have a problem with my intended carb setup on a 13B. Basically I have the racing beat upper inlet manifold and dellorto 48 carb, but i do not have the 4 port lower.
I am struggling to find one (at the right price) but i have a few stock 6 port lowers that i could use.
Are these the same fitting, just with mismatched front and rear ports? In which case will the 4 port engine run for now on the lower 6 port manifold?
cheers for your help
