Oliver:
If it is in fact a vacuum leak, then you can use an *unlit* propane
torch and
spray propane around all the manifold seams for the carbs with the engine
running. When you are close to a leak, the idle speed will go up by virtue of
the increased amount of fuel going into the engine.
Some people use starting fluid rather than propane, although I have not
tried
that personally.

Subject: [6pack] vacuum leaks
hi, all.
1972 tr6, triple carb, gp3 cam, shaved head, etc.
my mechanic tells me from the symptoms - idles sometimes at 1800, sometimes
800 or lower, that I have a vacuum leak.
is there a good way to trace that down? the spare dizzy is in the car right
now; it has the vacuum advance (and points). the rebuilt one is ready to go
(pertronix, recurved, no vacuum advance, etc). follow up question - should I
put that in first? and what do I do with the vacuum line?
thanks!
