How To Start Lawn Mower Without Primer Bulb

We know that a primer bulb transmits gas in the carburetor bowl to turn the mower on.  But on the other times, the carburetor bowl remains empty and there is no gas remain in the bowl.

A primer bulb is generally made of rubber or plastic. And starting a lawn mower without a primer bulb is an easy process. It approximately takes 5-6 minutes to complete the task.

First things first. You know some equipment that is required for this type of work. Let’s have a look at what we will require to start a lawn mower without a primer bulb.

Tools required:

  • A screwdriver
  • A starter fluid
  • Hand gloves 
  • Googles

Steps to follow:

Step #1: Prepare The Lawn Mower

Take the lawnmower into a flat surface. It will make your task easier and comfortable. 

Step #2: Activate Parking Mode

Take the lawnmower to the parking mode. This will prevent the lawn mower from being suddenly turned on.

Step #3: Find Out Air Filter

Now, find out the air cleaner. Most of the time, the air cleaner is on the engine side. Note that if you look inside the air cleaner chamber of the lawnmower, you will find the air cleaner.

The air cleaner is covered with a lid on top. And the cover is attached to the lawn mower body tightened with screws. 

Step #4: Remove Screws

Take the screwdriver and unscrew the screws by rotating them anticlockwise. Carefully store the screws for repositioning. 

Step #5: Bring Out Air Cleaner

Bring out the air cleaner from the air cleaner chamber. Make sure the air cleaner is not damaged in any way. When you withdraw the air cleaner, you will see the air cleaner chamber completely.

Step #6: Spray Starter Fluid

This time, take the starter fluid and spray it in the hole of the air cleaner chamber.

Step #7: Reinstall The Air Cleaner

Immediately reinstall the air cleaner into the air cleaning housing and place the cover. The reason for doing so is because the spray is volatile and it goes away very quickly. 

However, make sure that the air cleaner is properly installed. If you place the air cleaner into an inverted position, it will prevent the flow of air.

Step #8: Start The Lawn Mower

Now turn on the power of your lawnmower. The lawn mower will be launched shortly. 

Step #9: Set The Air Cleaner Cover

Tight the air cleaner’s cover screws using a screwdriver by rotating them clockwise.

Done. Now you can use the lawn mower without a primer bulb.

Cautions :

  • Wear hand gloves and goggles for safety purposes.
  • Go through the user manual before starting work. It will help you to avoid any kind of unforeseen incidents.
  • Be very careful in operating the screwdrivers.
  • Keep your children away from the lawnmower when you are repairing anything.

Final Verdict:

Starting a lawn mower without a primer bulb is an easy task. But always try to be quick when you work with the starter fluid. Since starter fluid is a volatile substance, rapidity is very important here.

If you follow all the steps described above, it will make your task easy and error-free. If you are unable to start the lawnmower after following the process, you may have to replace the primer bulb or take help from an expert technician.

Now, it is your turn. Hopefully, this article has given you all the necessary information on how to start lawn mower without a primer bulb.

I bought a 20″ Bolen push mower 2 years ago late in the year and put no more than 3 hours on it. I ran all the fuel out the last use so I could store it. I could not get it to start the following spring and oddly enough my next door neighbor has the same problem with his. What a piece of garbage. I borrowed a mower last year as my dad had an extra, but I will have to purchase a new one this year. I have never had a mower especially with a Briggs engine that is that kind of garbage.
