I figured it out by turning the screw in until I had black smoke coming out. Then the light bulb went off. I then turned it out until it ran good.
I'm not sure how yours works so turn it slowly until the engine starts to act up. If it is too rich you should be able to smell it or see black smoke. If it is too lean the engine will start to sputter & may die.
Just go slow - take small 1/4 turns until you get it figured out. You are on the right track - almost there! | | |
