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.
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 .....
