Ooh ok ... And since its 2 stroke i can plug up the hoses from the oil pump and just mix it stright in the gas tank?
Yes, get a air filter so it cuts off some air then you can tune it using that AIR RATIO SCREW.
As for the Oil Pump If it is working I would leave it alone they usually do not go bad. But if you want you can plug it up at the carb and any vaccum going to the pump as well and MIX the oil with the gas. But remember you will always have to carry some 2 stroke oil so when you fill up at a gas station you have to add the oil. AND YOU ADD the OIL FIRST then add the gas that way it mixes it. If you fill up then add the oil the oil will not be mixed.
