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
Maybe no juice in the battery.
Your flywheel key might be sheared
on the carb there is a plate that moves when you throttle up and returns to a stop screw when throttled down. This stop screw is the idle adjustment, turn it in until you reach your desired idle rpm.
Turn the flywheel to BDC (bottom dead center) as you continue to turn the flywheel into the combustion stroke, it will be the first valve to move.
To adjust the carburetor on a 24 hp Briggs & Stratton Intek V-twin engine, first ensure the engine is off and cool. Locate the adjustment screws, typically found on the side of the carburetor; one is for idle speed and the other for mixture (if applicable). Turn the mixture screw clockwise to lean the mixture or counterclockwise to enrich it, making small adjustments while observing engine performance. Finally, adjust the idle speed screw to set the engine to the desired idle RPM, ensuring a smooth operation without stalling.
Allow the engine cool off for 15 - 20 seconds. Position throttle to full speed and turn ignition switch off. This will reduce the vaccum through the carb thus drawing less fuel into cylinders.
There is a large allen head pipe threaded set screw (oil Plug) located in a hole under the engine . Remove to drain oil. Becarefull when replacing plug not to over tighten it will crack the case if you turn in to tight.
If the engine turns over freely with the sark plug out, then check for loose,rusty,or corroded connections from the headlights back too the battery.Even the ground wires throughout. recheck with a fully charged battery (12.6 v)
