Carb cleaner and O-Rings

[texactii at csonline.net]

Tom - you mentioned using carb cleaner around the injector
seal o-rings, while you would be in the process of chasing
down a leak.  Carb cleaner will deform the o-rings.  If
you want to check to see if there is a leak around an
injector seal, get a butane torch  bottle, with the nozzle
(found at hardware store - used for repair copper pipe).  Don't
light the butane, just open the nozzle slightly and point it close
to the injector seal.  If there is a leak, the butane goes in,
the idle picks up.  Use caution to not let it ignite from sparks
or the exhaust manifold.
