Most IPLs give ya enough info to see where the parts go/fit, no? It shouldn't be that complicated. As for the oil seepage, the only thing you can try is tightening up the cyl base bolts. Prolly be better off pulling the cyl. and slapping a ring/s in it and a new gasket. I always use a spray sealer on two stroke gaskets! Hy-tack or Copper coat.
