i just replaced the p&c on an 028 super did the vac test, passed at 10 psi great. Went to do the vac test, and not so much. I’ve read that crank seals are usually the culprit for this so I slathered some grease on both of them and no change. I can hear some whistling, my next culprit would seem to be the impulse line, does this sound reasonable? Or could it be something else? I’m using the mitivac with a cone fitting ran through the impulse line to test with. I dunked the saw in water earlier and no pressure leaks.
