Stopping Constantly

This is the most annoying problem that constantly happens with the Stihl BR 430 and all other similar backpack blowers. In this case, the blower starts well but won’t stay running. This issue is a little troublesome, so you’ll have to perform multiple troubleshoots to fix it.

The reason for this problem can either be a carburetor or fuel filter. Afterward, you need to find out which one is the main problem maker.

Fix Carburetor – Anyway, after Stihl BR 430 troubleshooting, if you found the problem is the carburetor. Then it’s surely clogged or scattered. When the carburetor is clogged, it continuously evaporates the substances and makes the fuel path greasy.

In that case, clean the carburetor with a good cleaner and reinstall.

Another way, if the carburetor is simply scattered, then remove it from the machine. Check the carburetor adjustment; if it’s solvable, then re fix it; otherwise, replace.

Fuel Filter – Though this isn’t that common, still it’s another big reason which won’t keep the machine running. Likewise, the problem is clogged fuel fuller. Basically, old fuel evaporates and makes it clogged. The solution is cleaning the filter and reinstalling it.

Not Starting

Mostly this ‘not starting’ problem occurs when the blower gets old. But this can happen even in the new machine. Though you’ve got enough fuel, the blower isn’t starting. What is the reason behind this? The reason can be the flywheel key as well as the spark arrestor.

Basically, the flywheel is situated near the crankshaft. If accidentally the flywheel discharged from the woodruff key. It won’t fire up the engine. Similarly, when the Stihl BR 430 Spark arrestor got damaged, it couldn’t create the spark. Without the spark, the engine won’t start

To fix this issue, you need to reach that flywheel key position and remove the flywheel. If it seems ok, then reassign to its position. But if the flywheel gets damaged, then replacing it’d be the best idea—the same solution for the spark arrestor.

Weird Noise Problem

This is another critical problem to fix. The hardest part is to find out where the noises are coming from. In most scenarios, the sound came from the faulty engine. It means when you try to start the blower, the defective engine can’t deal with any loosened part. That’s why it happens

Go through troubleshooting to the engine. Apply synthetic multi-purpose grease to the engine, specifically those places where the friction occurs. Other than that, tight all loose parts of the engine. If any part gets damaged, change it.

Losing Power

When the machine loses its power, it can barely perform. The users wouldn’t get that flexibility, and the performance would drop in half. Which part is particularly responsible for this issue? Actually, there’re many points to look at. The problem can be fuel filter damage or carburetor dysfunction.

But if those are right, then the problem must happen because of the spark plug. Once again, we’re not talking about spark arrestors; we’re talking about spark plugs. You wouldn’t believe how fast they can get dirty. Either clean or replace it. Hope the power will come back again.

Performance Dropping

This isn’t a regular problem where a specific part is responsible for the inconvenience. Here the whole machine is possible for the performance dropping. Basically, it happens to the old blower which has been used for ages.

But if anybody experienced that with the new blower, that’s also ok. This particularly happens from lack of servicing and taking care.

To get back the better performance, you’ve to send it for servicing, where they’ll build and refurbish the entire blower. It also can happen because of an old/damaged engine. In that case, just replacing the engine is the only solution.
