On my 1990 pro V yamaha engine?

Question

thus my oil injector pump have an adjustment on my linkage to pump more oil into the cyclinder or does the pump is already pre set

Answer 1

a 1990 and you haven't disconnected that oil injector yet??? you should... you just have to put a new fuel pump in... if you can't then take it to a shop and tell them you want to disconnect your oil injection system and manually mix the oil and fuel... you do realize that if you are not getting enough oil or even any at all, you can blow your engine right? or score the cylinder walls which will cause you to lose compression and performance... you engine is almost 18 years old....

Answer 2

I believe there is an adjustment but it comes set from the factory and is double checked when installed on a boat.
