Afterwards, I put the petcock in some hot soapy water and cleaned up the worst of the dirt:
Forgot the pictures, but I took off the plate which holds the lever in place, took out the small four-hole gasket and the V-Ring on the lever. Lubed up the gaskets with some vaseline, including the membrane on the back (which I left in place for fear of destroying it), and after closing up the back side, put it into the ultrasonic for approx. 2 hours (sans gaskets of course). Turned out nicely:
As with the other petcock, I wrapped some teflon around the nozzle's base for a tighter fit:
Again, no after pictures, but suffice to say, the petcock doesn't leak at all, flows nicely as far as I can tell, and the vacuum membrane works as intended. No more leaky carbs! (Still a hanging idle, but that's another topic.)
Edit: Teflon tape is DIN 30660 / EN751-3 FRp, that's the one which is resistant to oil/gasoline, for fine-pitch threads.
