oil leak out the exhaust?

my yamaha waverunner is not running to good. and it also leaks a fair amount of oil out the exhaust while it is running.Is there any kind of adjustment on the oil pump or carberetor or not.It is a 96 model twin carb two stroke.

two strokes have no vavle guides or seals bg

replace exhaust gasket and torque manifold bolts to manufacturers spec.

do check pump as above

make sure youre using current 2 stroke oil tc-w3 is approved,fresh regular gas and new spark plugs should breathe new life to your waverunner.if you just changed your throttle cable receck alignment marks

Oil out of the exhaust is not a good sign......vavle guides or seals worned out .....bad or stuck piston rings ...run a engine comppression check .....
