How do you bypass oil pump in PW50 ? Oil/Gas ratio ?

[stalefish]

I want to just run premix in the PW50 the oil pump pushes so much oil through that it is leaving a wet film in the exhaust. So what so I do to by pass the pump. I hear of a different throttle cable or something to that effect. and unhook and plug the reservior. Please can someone clarify the procedure a little.
And after I accomplish this what ratio do I mix oil to gasoline on the PW50?

Why don't you adjust the pump stroke for less oil?

I am not quite sure of how this is done? If it would be easier to do, I would rather go with that suggestion. Can you help , do I need special tools?

if the cable is adjustable adjust it- loosen it make sure it is opening less-but not too much
check the plug after adjusting it ,and make sure its not too lean
the plug needs to be tan
either injected ,or premix
check the manual
