6 Steps On How To Bypass Primer Bulb On Weedeater
The primer bulb is basically an air bulb on a weedeater that forces the gasoline into the carburetor to get the engine started.
You see, each push of the bulb sprays a fine mist of gasoline along with the air needed for the weedeater to start.
As the air bulbs are made of plastic or rubber most of the time, it eventually cracks or breaks after long term usage.
To repair this you just need another bulb and replace it. But you might face a situation when there’s no bulb available near you and you need the weedeater turned on right away.
However, the repair we’re going to show you is just going to take a few minutes only to get the weedeater started.
So, let’s check out how you’re going to bypass primer bulb step-by-step-
Step 1. Remove The Screws
You’ll notice that there are two screws on each side of the air bulb. You need to remove those two screws from the metal plate using a screwdriver.
However, you might also find flat -head screws or Philips head screws. It basically depends on the brand of your weed eater.
After you’re done removing the screw, keep them aside to a certain place so that you don’t lose it.
Step 2. Pull Away Air Bulb and Metal Plate
Now, you need to pull the metal plate upward to remove it from around the air bulb. Grab the previous defective air bulb and pull it straight upward.
If you notice that the air bulb or the metal plate is stuck, don’t worry. You can use a needlenose pliers to remove them.
Step 3. Clean The Air Bulb Seat
You see, a lot of dust and debris might often pile up at the air bulb seat on the weed eater.
If those enter the carburetor, there’s a high chance that they might do great damage to the inside mechanism of the weedeater.
Step 4. Put The Polythene in Place
It’s going to sound weird but this is what you need to do. You need to put the polythene under the metal plate where the air bulb was.
Now, push outside from the hole using your finger. This will create like a ball of polythene and it will act just like the primer bulb.
Step 5. Screw The Metal Plate Back On
You need to screw the metal plate back on now using the two screws to tightly fit it into place.
Make sure that it’s too tight to let any outside air get into that tiny ball of polythene.
Step 6. Press The Polythene Ball Few Times
Now you need the DIY bulb you’ve made to be ready so that you can start your weedeater right away.
As soon as you screw it tightly, you’ll notice the gas piling up inside the ball of polythene and that’s exactly what we want.
All you need to do it keep pressing that little ball for quite a few times till you see bubbles in the carburetor line. Because that’s when you know your weedeater is ready to start.
Now try to start your weedeater. It might not want to start at first, but it’ll start running after a few attempts.

Frequently Asked Questions
Question: Why is my primer bulb not working?
Answer: You see, when your primer bulb isn’t working, it may be a problem with the bulb itself. Also, people often face issues with the fuel lines that feed fuel to the bulb or both. Often fuel lines hardened and cracked and they let in air. That air is what makes it impossible to draw the fuel into the carburetor properly.
Question: Which fuel line goes to the primer bulb?
Answer: You’ll notice the clear pipe which is the fuel intake line, runs from the top of the carburetor. And it goes to the short post on the back of the primer bulb. The blue line a.k.a the return line comes from the long post on the back of the primer bulb and goes into the bottom of the fuel tank.
Question: Why is my carburetor not getting gas?
Answer: The most obvious reason could be the supply of zero fuel at your carburetor. Also, it can be a simple issue like a fuel filter plugged so tight that no fuel can pass through. Nevertheless, a hole in the fuel line on the tank side could also cause the fuel pump to such air instead of fuel from the fuel tank.
