This Do-it-yourself job can be simple but it may take time for you to find the settings you want. Today we will show you how to adjust the carburetor of a 4-cycle weed eater. It is important to keep tools and equipment well-kept so that they will be useful to you for a longer period of time.
Regardless of the reason adjusting your carburetor correctly is important and worth knowing to save on repair costs. When doing our own tasks budget is very important, and money is already being saved by doing the job ourselves, consideration must be made for the tools needed.
Tools and Substances Needed for Adjusting the Weed Eater XT260 Carburetor
- Splined Adjustment Tool (alternatively a flathead screwdriver with a splined connector attached)
- Spark Plug Wrench
- Fresh Gasoline
Before adjusting the carburetor, checks need to be made to determine the trimmer is starting and functioning properly.
Checks Before Making Adjustments
- If the trimmer was left for a long period of time since the last time it was used, then the fuel will need to be changed. Drain the stale gasoline from the trimmer and replace it with the fresh one
When it is left for a long time greasy residue starts to collect which blocks up the trimmer. If you see this residue in or around the fuel tank then the performance would be negatively affected, it may not even start. Replacing the gasoline and cleaning the greasy areas are the best options to prevent further buildup of grease from harming the trimmer.
- If the trimmer was used fairly recently then check the gasoline for water by draining it into a container and looking for pockets of water, if you find water, change. When water is present in the gasoline it reduces performance and causes damage to the engine.
- Remove the spark plug using the wrench and inspect for grime or carbon, then clean or replace as required.
Once these examinations are made and the results are favorable then adjustments can commence on the Weed Eater carburetor.
Adjusting the Carburetor
On the right side, beyond the starter pull cord, the trimmer has special screws in holes close to each other on the carburetor. They can be adjusted to enhance the performance of the trimmer at low and high speeds. The screw labeled “LO” adjusts the fuel use of the trimmer when the engine is idling while the screw labeled “HI” adjust the fuel use at full power. These special screws were made with the intention to prevent and reduce unwanted tampering of the trimmer so a special tool is required to turn them.
- Pull the cord to start the trimmer, if it does not start then using the splined adjustment tool turn the LO screw anticlockwise by a quarter of a turn and retry.
- Repeat until the trimmer starts.
- Continue turning the LO screw anticlockwise by a quarter of a turn until the trimmer idles effortlessly.
- If the trimmer is spluttering at full power the HI screw needs to be adjusted.
- Turn the HI screw all the way clockwise.
- Give it one full anticlockwise turn and then check if it still splutters at full power
- Continue turning the HI screw until it can run smoothly at full power.
- Once satisfied with the adjustments let the trimmer cool down for four hours or more.
Trial and error are involved in adjusting the Weed Eater XT260 carburetor but once everything runs smoothly you can rejoice. The trimmer is ready to return to the field and eager to complete its duty.
