[TR] Slow idle drop

Ed,
 
I'm assuming that your emissions equipment (air pump, gulp valve, etc.) has 
 been disconnected....if not, a big culprit behind the symptoms you 
describe  would be a faulty gulp valve.
 
Often,it helps to have the engine running when you check linkage adjustment 
 problems.  Have someone depress and release the accelerator pedal while 
you  observe the operation of the linkage.  Look around the individual carb  
throttle plate linkages very closely to be sure they're promptly returning to 
 their stops.  Once you've ruled out any linkage problems, remove the air  
cleaners and check operation of the air valves to be sure one or both aren't 
 hanging up.  Just for kicks, spray a little carb cleaner around the points 
 where the throttle shafts enter the carbs.....while the engine is 
running.....if  the rpm changes noticeably, the rebuilder may have not replaced the 
rubber seals  around the throttle shafts letting air into the carb changing 
the mixture at  random amounts depending on how the throttle shaft moves.

I have  inspected the linkage and don't find that it is hanging up
anywhere. Is it  possible though that it could be something with the way I
reinstalled the  linkage?
