um idk what brand but its 2 stroke oil.
how do i do a leakdown test? i put diesel in the top to clean it out a few days before i put it all together, and it didnt leak into the bottom so im sure the case is sealed, it has new gaskets for cylinder, head, reeds, and exhaust, and i had the head resurfaced so that should be fine. the one between motor and cylinder is paper kind of so that should seal fine.
I forgot to mention i did a whole top end job on it, i rebuilt the whole engine basically except the transmission, replaced all the clutch and gears on the side and cleaned that stator and everything.
And yes brand new uni filter with uni oil.
I also cleaned the cab which was clean already but i clean em all the time so im sure i cleaned it pretty good.
