Make sure you install your crank seals the correct way, don't put them in backwards. Then when your done, perform a leak down test to make sure everything sealed up the way it should. You would be dam surprised on how many motors fail the leak down test.

Make sure to grease the inside lip of your seals and lube your cylinders,pistons,and crank bearings with two stroke oil.
