Insufficient Priming: A Potential Culprit for Non-Starting Gas Blowers

With gas blowers, one common issue that may prevent them from starting is not pressing and releasing the primer bulb enough. Typically, you should perform this operation about 10 times. The purpose of the primer bulb is to draw fuel into the carburetor, allowing the engine to start.

Overdoing or underdoing this step significantly impacts the blower’s ignition. Therefore, if you’re experiencing difficulties in starting your gas blower, I recommend that you pay attention to your priming technique.

• Importance of Properly Mixed Fuel in the Fuel Tank

Providing the appropriate fuel for your gas blower is as essential as putting unleaded fuel in an unleaded-only car; it’s non-negotiable. The fuel tank of your blower must be filled with mixed fuel, a combination of gasoline and two-stroke engine oil, in the correct ratio.

An improper mix will likely impede the blower from igniting properly, resulting in the blower not starting at all. Click here for more information on proper fuel mixing.

• The Threat of Old or Improperly Mixed Fuel

Much like how expired food spoils, the quality of gasoline also degrades over time. Old or improperly mixed fuel can become a major roadblock in getting your gas blower to start. Often, the fuel becomes too thick or changes state due to separation of components, making it unsuitable for use.

It is then recommended to drain out any old fuel present in the tank and replace it with fresh fuel. This simple task can drastically enhance the blower’s performance and ensure optimal function.

• The Need for Air Filter Inspection and Maintenance

Clean air is as vital for the smooth running of your gas blower engine as it is for us humans.

Impact of Old Fuel in Leaf Blowers

First and foremost, it is crucial to understand the effect of old fuel left in a leaf blower. The antiquated fuel can transform into a thick sludge, hindering the blower from starting. This is primarily due to the volatile components in the fuel evaporating over time, leaving behind heavy, viscous residues.

This poses a considerable threat to the lifespan and efficiency of the leaf blower. In fact, such heavy residues can potentially clog the carburetor of the leaf blower.

To avoid this issue, I recommend removing any fuel that has been in the tank for more than 30 days. Furthermore, ensure to always use fresh fuel when getting your leaf blower ready for use.

• Two-Stroke Leaf Blower: Fuel Separation Issues

Two-stroke leaf blowers are not exempted from the impact of old fuel. If these machines are left unused for a substantial amount of time, they can experience a phenomenon known as fuel separation.

This often leaves a layer of oil at the bottom of the fuel tank, interfering with the normal operation of the blower when you attempt to start it.

The solution to this problem resides in shaking the leaf blower before starting. This re-emulsifies the oil and the gas, recombining them into a more homogenous mixture that can be effectively drawn into the carburetor for combustion.

From my experience, it does indeed work like a charm, ensuring a smooth start every time you attempt to power your two-stroke leaf blower.

For further insight on this, you can check the U.S. Energy Information Administration’s page which gives a more detailed explanation of fuel and how it works.

• Importance of Priming Before Starting a Leaf Blower

Priming your leaf blower before starting is a procedure that is often overlooked. But it suffices to say that starting your leaf blower will be challenging if you fail to pump the primer before pulling the starter cord. The primer bulb serves to draw fuel into the carburetor to assist in cold starting.

The lack of priming results in a lack of enough fuel in the carburetor for the engine to start. Therefore, I always recommend pumping the primer bulb a few times before pulling the starter cord.

• Understanding Non-Gas-Powered Leaf Blower Start-Up Challenges

While gas-powered leaf blowers suffer largely from fuel-related issues, non-gas-powered leaf blowers have their unique array of start-up concerns. Among these, the most common are being unplugged, having the power switch off, or having an uncharged battery.
