Walt Well Known Member Jul 17, 2011 #4 Symptom would be higher than normal EGT on the one with a leak due to the leaner mixture (sucking air in thru the leak), engine may run rough.

A aerhed Well Known Member Jul 17, 2011 #5 Should be leaner than usual at idle right? The greater the drop across the throttle plate, the more it'll suck throught the leaky lines.
