Doug,

Check the throttle position switch (or switches) to make sure it's working
correctly in the idle position.  If you have the dual purpose switch a good
cleaning may be all it needs.  If the problem is still there check the Temp
II Sensor with a multi-meter and the warm air valve (not sure on the name) by
squeezing off the hose going to the AFM.

P.S.  We're supposed to have a Postal Service sort of day tomorrow in
Cincinnati -- rain, snow, sleet, and hail!!!

>>Hi Gang,

     Once again I turn to the collective wisdom of the list. My 84 Westy runs
roughly after start up --- sounds like it's missing and has low power until
I've
limped it along for about five minutes. Then it will run fine ---- but if I
let
it idle for a minute or so it will 'surge' up and down until it dies. Both of
these symptoms started at the same time a couple of days ago. Distributor cap,
wires and plugs are all very recent. Any and all input greatly appreciated.

A Great Weekend to all

P.S.: We've got a winter storm watch happening here ---- 6 inches of snow
coming
to the outlying areas ---- and I was wearing shorts weeks ago!!<<
