The first time I removed my carbs, I stuck my finger in the Int. manifolds to feel around for how well they fit to the head and I found both sides badly misaligned, there is enough slop in the two 6mm (?) bolts that hold them on, that I was able to manipulate the heat spacer, the alloy tube and the fit to the head a lot better then as they were assembled at the factory. Locating pins or just closer tolerances would make sense on this component of our engines, IMHO
