[6pack] vacuum leaks

[Navarrette, Vance]

	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.

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!
