Introduction
Before starting this replacement make sure your engine has been turned off and cooled down prior to touching the machine.
This is one of the most common issues that can be easily fixed. This problem usually occurs when grass, twigs, and other debris slowly makes their way up to the engine when it is chopped up by the blade, and after some time the debris gets all stuck up inside of the carburetor and causes the O-Ring to wear out. This causes clogging in the fuel and air filter and makes the mower’s engine less efficient. This guide can be followed by anyone and be completed at home with a few easy steps and will make your lawnmower run like new!
