Carburetors can wear out for multiple reasons. If your engine is hesitating, stumbling, stalling, letting out black smoke, or has a hard time starting you may need to replace the carburetor. As intimidating as it may look, replacing a carburetor is an easy task that can be completed in just a few steps.
Below is a guideline to help you replace your carburetor. Be sure to check your owner's manual for specific recommendations for the power equipment you are servicing.
1. First remove the two screws holding the top of the air filter on.
2. Remove the air filter and the four bolts holding the air filter base on.
3. Remove the two bolts holding the muffler on and remove the complete muffler.
4. Remove the two screws holding the choke/throttle control on the gas tank. Move the assembly to the side.
5. Now you have access to the bolt holding the throttle linkage to the carb and the two bolts holding the carb to the engine. Remove all three.
6. Lastly remove the bolt on the bottom of the fuel tank support bracket then remove the carb and tank as an assembly.
7. Before you discard the old tank and carb be sure to remove the carb breather tube with the rubber boot and the speed set assembly from the old tank bracket. They both need to be transferred to the new assembly.
8. Install the speed set assembly on the new tank which is held on by only one screw. Then install the new carb with the new gasket onto the new fuel tank along with the breather tube and elbow from the old carb.
9. Install the new carb and tank assembly onto the engine following the opposite order that you removed them.
