if a regulator plunger is sticking and it just came back from service, is there a way to prevent it from sticking without sending it in? maybe storing the plane upside-down? (my engine is mounted inverted) or could i take the regulator screw out and lube it with the oil that comes in my glow fuel? any thoughts?
thanks,

Give Richard a call at service in the morning. 775-782-4562

thanks.

i just realized that i would not be able to contact him all this week, so on the advice of some other ys owners i simply took the regulator off and cleaned it with glow fuel, which should leave some oil there. now, my question. i am pretty certain i got it right, but wanted to check with you first. on the regulator membrane, there is a little lip, in a circular pattern which alows for the regulator membrane's center to move in and out without streaching. the raised part of the lip should be facing the regulator screw right? i seem to remember it being that way and the regulator body has a chamfer in the right place for it, but i just wanted to make sure i did not royally screw anything up.
thanks,

The regulator body has a bump on the front side at the parting line. Always make sure it mounts toward the front of the engine. The diaphragm doesn't matter which way it's installed.
