Mike-
I have always experienced the same problem on my 2L (N17 needles). Mine
will keep power while aggresively accelerating, but if I hold a steady
speed, it tends to surge. I hate to do this, but if I'm on the highway I
pull the choke out part way. You may try this as it will help determine if
you are truly getting enough fuel. The choke cleans it right up, but I hate
the chance of running too rich and washing my cylinder walls. I've
experimented with richening the carbs dramatically, but I get the same
result (also required radically increasing idle speed setting to run-not too
practical). At first I thought the needles were causing the lean condition,
now I'm not so sure. Any thoughts?!
BTW, manifold vaccum is good through all RPM's.
