I'm puzzled (doesn't take much). What version of HS4's are these with the three
fittings? I just finished plumbing mine in (AUD 52's) and they only have two
fittings on each carb. The plumbing, as seen in photos in Clausager and from
the
Moss catalog, shows a fuel line from the tank to a tee at the rear carb, a short
piece of fuel line from the tee to the rear carb and a longer piece of fuel line
from the other leg of the tee to the front carb. My curiosity is whetted. In
what
version of HS4's is the fuel first routed to the front carb?
