thanks for the reply... actually it is usually the opposite, pull up to stop and
revs up to 4K, and stays until I slip clutch or leave intersection...

If you pull up to a stop, is the idle high & eventually it drops? If so, you
could possibly need a vavle adjustment (tigh intake valves).

throttle it runs good and has good power, but at an idle, it some times revs up,
around 4K or so, and the only ways to bring it down is to slip the clutch... I'm
thinking some sort of a vaccum leak, but have been unable to find it, I've taken
the carbs off numerous times and blown out passageways and orifices... any help
would be appreciated, it is a 82 XJ550 Maxim...
