5 Most Common STIHL BR 800 Problems & Troubleshooting

You will need efficient tools to guarantee the best performance in all your gardening tasks. You will need a powerful mower, a chainsaw, and, eventually, a blower. Using the Stihl BR 800 allows you to enjoy a big blower’s perks without worrying about weight.

The Stihl BR 800 is a backpack blower with a lot to offer. This includes the powerful 79.8 cc engine and the ability to imitate a wind’s velocity of over 225 mph.

Despite these fantastic features, the cutting-edge blower has a few flaws that leave users dissatisfied. The most common Stihl BR 800 problems include starting difficulties, starter rope, and fuel issues.

This article will give you an in-depth look at the most famous problems with this blower and the most reliable fixes for them.

The Most Common Problems with Stihl BR 800

Stihl BR 800 is simple to understand, use, and maintain. But like any other small-engine gardening machine, it might have some starting issues. Also, there could be issues related to improper fuel and oil blends. But in general, all these issues can be easily managed with DIY procedures.   

1. Starting Failure

This is a common issue with brush mowers as well. It will help to inspect the spark plug when your engine is not responding to multiple starting attempts. A minor engine flood could lead to a lack of firing in the plug. A damp spark plug will not work, and the whole engine won’t run.

Usually, this problem can be fixed easily if the plug is not damaged. You can take the spark plug out and wait for it to dry. Also, you can dry it if you are in a hurry. Then, try it once more. If the spark is still in good condition, it can fire. Otherwise, you will need a new one.

While you are at it, it is better to thoroughly check the whole fuel system to determine the cause of the leak. Usually, a damaged fuel hose or line could be behind the issue. In this case, you will have to replace it. Also, take a look at the choke lever. Make sure it is fully closed. If it is open, the machine may not start.

2. Repetitive Stalling

This issue is not one of the only Stihl BR 800 problems. It happens on various models of Kubota zero-turn mowers. If the engine runs usually but then stalls or idles abnormally fast, it is typically a cylinder issue—the cylinder malfunctions when the air level goes beyond normal in the carburetor.

So, taking a look at the cylinder and the pistons inside it can help you detect the malfunctioning source. If the cylinder and its piston fail to balance the air and fuel blend, the vacuum power won’t be sufficient for combustion. So, getting a new pair of those can be your way out of getting the right levels of vacuum inside the leaf blower.

3. Difficulty in pulling the starter rope

Ideally, you can easily pull the rope, and it should retract or rewind fast, too. But when you experience things differently, you will have to inspect the starter mechanism. First, you should take a look at the components to eliminate uncleanliness. Clean up any buildup, as it could prevent the motion of these parts.

Also, you will need to check the pulleys. The rope will not pull or retract if they are damaged. Also, you should inspect the spring that is attached to the pulley. If the spring is broken, you will need a replacement. If you cannot determine the exact reason for the rope lag, you can get another starter assembly to spare the effort.

4. Engine failure to deliver maximum power

When you use your Stihl BR 800 for quite some time, you will get to know its power capacity. So, it will be easy for you to recognize its full power performance. When this leaf blower can no longer do this, you will have to look at different parts. This includes the air filter, fuel filter, and carburetor.

When any of these parts become clogged with dirt or debris, the power of this blower will decrease. A clogged air filter will limit the required air for a proper fuel combustion process. So eventually, the performance of the blower will become weaker. To solve this issue, you will have to clean this filter or get a new one intensively.

Another vital component to check when your blower bogs down suddenly are the fuel filter. It is supposed to deliver fuel without any debris in the body of the blower. When this filter is damaged or clogged, the fuel will not be as clean as it should be. You will have to repeat the same routine you did with the air filter.

Also, you must check out the carburetor. Sometimes, it isn’t working correctly due to uncleanliness. You will have to ensure its cleanliness. Also, internal damage could be inside the carburetor that requires replacing the whole carburetor.

Also, the problem could be as simple as an improper carburetor adjustment. To fix this issue, you can shift between high and low options to encourage the blower to reach its maximum power.

5. Fuel leak

It is never a good thing for a leaf blower to leak fuel. There is no need to mention that it is hazardous too. If you suspect a gas leakage, you must inspect the whole fuel system of your Stihl BR 800.

There could be a worn-out or damaged primer bulb. This bulb can cause fuel to leak into the body of the blower without pumping it into the carburetor. Also, broken fuel lines can be the culprits of a gas leak.

Also, you will have to inspect the fuel tank and its cap. If there are cracks in this tank, fuel will severely submerge the body of the leaf blower. Also, a faulty cap will not be able to contain the gas inside the tank.

So, in the case of any faulty, damaged, or worn-out fuel system component, you will have to get a whole new replacement
