Hello;

I have been lurking on the list for a while.


Tracy, I'm curious what kind of rpm range (idle and top rpm/hp) you saw
with your
original carb setup running on only the centre carb and intermediate
housing ports?


Has anyone ever joined the intermediate housing ports by removing some
of
the material between the ports in the housing to make a larger single
port
and runner?
If so, did it help or adversely affect operation?

My thought was that I would run a single intake runner to the centre
housing
which would simplify the intake and provide a more constant flow in the
runner
as one port should always be open with surges when both ports are open.
(may also reduce tuning potential)


Cheers
Cary
