If the engine starts: Let the engine warm up for about 5 minutes and S-L-O-W-L-Y close the needle valve (rotate clockwise) until the engine starts to stall for lack of fuel. Then open the needle valve (rotate counter clockwise) until the engine starts to stall because of too much fuel. Set to half-way between the two extremes. If the engine doesn't start: Close the needle valve by screwing it in clockwise just to a point where you feel it stop - DO NOT FORCE IT!! or you will ruin the tip. Open the needle valve about 1-1/4 to 1-1/2 turns. This should be okay to start the engine and then follow the procedure above. If the engine hesitates under a load, open the needle valve about 1/8 turn for a slightly richer mixture.

This is the basic standard procedure with nearly all Briggs motors.

How do you adjust the carburetor on a lawnmower engine?

Go to your local autoparts store and by the rebuild kit according to your carburetor. Inside the box will be an exploded diagram of the carb which will make it relativly simple to rebuild First of all what kind of engine do you have. Briggs and Stratton or Tecumseh. If you have a Briggs & Stratton engine the factory setting on the little black screw is 1 turn out, Tecumseh engines 'usually' do not have adjustments. hope this helps
