The wall busted between the intake port and the oil galley on the head . It’s such a small hole you can’t see it ! Thats why it was hard to figure it out . Shinned a light through the hole and looked through the intake port and I could see the tiny hole and the light showing through . #howto #minibike #oilring #smallengine #tillotson #predator #pistons #greybuilt #whitesmoke #oilburning #inspecteverything
