[TR] Slow idle drop

[McGaheyRx at aol.com]

Move the throttle linkage by hand and watch for proper return spring action 
 when you let go
 
You should have a return spring on each carb  and a return spring on the 
throttle linkage.
 
A friend had a similar problem and found the return spring missing from one 
 of his 2 rebuilt carbs.
 
If it isn't that, I'd remove air filters - stick finger in mouth of carb,  
lift air valve with finger, make sure air valve drops quickly and firmly 
down  when you release it.
 
Hope this helps.
 
Cheers,
Jack Mc

I  recently installed professionally rebuilt ZS carbs on late TR6 engine.  
I'm
having an issue I hope to get some advice on.  After running at  speed, say
2500 to 3000 rpm, and then coming to stop, the rpm is very slow  to drop to
normal idle.  I would say it takes about 10 seconds to  settle down. The
problem is also evident when up shifiting, as the rpm  stays high between
gears.  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?  Or could it be that  the vacumn advance is not
functioning properly, or????

Looking  forward to suggestions.
TIA
Ed
