My original reply, quoted below Paul's reply, is hopefully not too far
offbase. My carb experience, although extensive, applies mainly to the HS4
carbs and not the HIF series. Bill's original problem was with the HIF
carbs and in my haste I did not take this in account. Instead of the nuts,
there is a jet adjusting screw on each carb.
Thus, the steps will be a bit different but I'd still check float height
and fuel mixture settings. Perhaps one of you HIF guys can detail out the
steps better - Bill says he'll be checking the carbs out today.
