Please remember that if your lawnmower is still under an extended warranty, be sure to ask the manufacturer if a clean-up is eligible for your machine if it’s still under warranty.
Cables should be removed
Grab the black plug (usually the one on your car) and pull it away from the engine directly. Please note that you may need to exert a bit of force to pull the plug up. Therefore, make sure not to push on the cable itself, as you might damage the cable if you do this.
With this plug installed on the engine, the engine is now ‘live’ and can start up suddenly. This is if the blades of the engine are moved or the mower is not functioning properly. Thus, this is a very critical safety precaution.
There is no reason not to remove the cable regardless of whether you will be working directly on the blades or parts of the engine. As a result, it may start to occur in the future as a result of this. The right thing you can do, no matter what, is to act as safely as possible.

If everything has been cleaned and all the parts have been installed, start the engine to see if the issues have been resolved and if the cleaning works.
Added carburetor, air filter, and throttle cable
Once your carburetor has been deep-clean, you should reinstall all of the pieces in their correct positions once you’ve done the deep-cleaning.
