hey guys i have a yak 54 with a 30cc gas engine and i just bought a smoker pump and i'm wondering if i need a special muffler or if i can just thread a nipple in my original muffler and hook my oil line up to it that way. also how do i stop oil coming out of the vent line when i'm flying with the pump off and the vent line would not be suckin air???
