My '87 westy is having an odd problem where it runs pretty rich (
stinky w/some smoke ) only AFTER warming up. I've checked the Temp II
sensor and it seems to have correct resistances  ( I can only guess
at it's temperature), the OXY sensors is giving about 0.6 volts once
warmed up.  AFM seems to move properly ( I didn't get it's resistance
as I moved it ....).   Throttle switch is works.   I recently had the
Idle Stabilizer box replaced. Does anyone have any ideas about other
things to check or what might be the problem?
