How to Replace Primer Bulb on Weedeater Featherlite SST25CE

From a mechanical perspective, a string trimmer is very similar to a lawn mower. They are generic names for Weed Eaters, and different manufacturers offer models that run on gasoline, electric, or battery power. A string trimmer is an easy-to-use hand-held machine that spins microfilament strings rapidly, making them strong and able to trim out the weeds which are harmful for your lawn.  As the old string wears out, new strings are automatically fed, displacing the need to maintain sharp metal blades.

However, you might need to replace some of the parts of the string trimmer now and then to keep it going. One of the most replaced parts is the Primer Bulb. so, today we are going to talk about how to replace the primer bulb on the Weedeater Featherlite SST25CE.

Replacing Primer Bulb on Weedeater Featherlite SST25CE

Weedeater Featherlite SST25CE

SST25CE is a very famous weedeater model of the popular Featherlite brand. A primer bulb on a weed eater forces gasoline into the carburetor to start the engine. In addition to gasoline, the bulb also sprays the air needed to start at the push of a button. Bulb use eventually deteriorates, cracks, or breaks because of the materials used in their construction. To start your weed eater properly, an air bulb that is broken or cracked needs to be replaced. Replacing the air bulb takes just a few minutes.

So, the techniques of replacing the primer bulb on this weedeater are given below:

Step 1. Install the Bulb On Carburetor

For the first step you need to set the bulb on the carburetor properly. Be sure you do not start the engine by accident by unplugging the spark plug wire. Because that might cause an accident.

Step 2. Remove the air filter cover and air filter.

On this step you will have to remove the cover of the air filter. For this step you must first turn an external knob to detach the cover. This will work for some of the models. And for other ones, you will need to remove the screws first. When you see the external knob, you will know what to do.

Step 3. Loose the Mounting Bolts

Loosen the mounting bolts holding the carburetor in place, using a screwdriver, usually a Phillips-head screwdriver. The carburetor sits directly below the air filter cover — recognize it by its center circular opening and two mounting bolts on each side.

Step 4. Pull the Carburetor Free of the Trimmer.

On the next step you have to make the carburetor free by pulling it out of the trimmer. Afterwards, you need to place it on a shop cloth in order to catch any fuel leaks while working on the system.

Step 5. Removing Primer Bulb.

The next thing you have to do is to remove the primer bulb. You should take utmost care when doing this, as it is the most important step. By using a screwdriver and mounting plate, you must unscrew the retaining ring that keeps the bulb in place. Each manufacturer has its own specific method.

Step 6. Installing new Primer Bulb

On the last step, you would need to set up the new primer bulb. This step requires that you remove the old primer bulb from the carburetor and replace it with a new one. The mounting plate or retaining ring must be slid over the primer, and the screws must be replaced to secure it in place. Following that, the mounting bolts for the carburetor must be inserted into the corresponding holes on the side of the engine and tightened. Once that is complete, the air filter and cover should be replaced. Lastly you can complete the replacement by tightening the knobs or screws and reconnecting the spark plug wire.

Final Words

Those were all the steps involved in replacing the primer bulb on a Featherlite SST25CE. By following the steps above, you will be able to do it on your own. In addition to saving you time and energy, you would not have to deal with any hassles when searching for an expert. Furthermore, you can do it at zero costing. So it is better to know the basic maintenance of your daily household machines so that you can fix it by yourself.
