How To Replace The Carburetor On A TPS25 Backpack Sprayer

The carburetor is the heart of your engine. Without it, nothing can function properly. In the Tomahawk 5 Gallon Gas Power Backpack Sprayer, the carburetor is located between the air filter and the engine housing.  

The carburetor sustains the perfect air to fuel ratio to keep the engine running smoothly. If the engine keeps bogging down and adjusting the carburetor does not seem to fix the issue, you will need to replace the old carburetor with a new one.


Learn how to replace the carburetor in your backpack sprayer with this guide:

What You Will Need:



Step 1:

Untwist the knob on the outside to remove the air filter cover.

Step 2:

Remove the air filter.

Step 3:

Use an Allen wrench to loosen the two screws that are holding the air filter cover and engine housing in place. This is located inside, on the back of the cover. 

Step 4:

Separate the back of the air filter cover and the carburetor from the two screws.

Step 5:

Dispose of the used gasket.

Step 6:

Remove the throttle and gas lines from the old carburetor.

Step 7:

Attach the throttle and gas lines to the new carburetor.

Step 8:

Slide the new carburetor and new gasket onto the two screws attached to the back of the air filter cover.

Step 9:

Align the screws with the holes on the engine housing.

Step 10:

Tighten the screws with an Allen wrench to secure the carburetor and air filter cover in place.

Step 11:

Insert the air filter.

Step 12:

Apply the air filter cover.

Step 13:

Twist the knob on the outside of the air filter cover to tighten.


With a new carburetor in place, your engine will be running smooth. Your backpack sprayer is now ready to use!
