Trying the chainsaw engine to start for a while as no response this engine has come out with? Well, it’s one of the commonly occurring problems of Husqvarna 545. 

This issue might take place due to various reasons including, lack of fuel, a faulty spark plug, or a clogged air filter.

How To Fix:

First, check the fuel level and make sure that your chainsaw has enough fuel to run. If the fuel level is low, restock the tank with fresh fuel. Next up is to check the spark plug and ensure that it is clean and properly attached. 

If the spark plug is dirty or damaged or even worn out, replace it as soon as possible. Finally, check the air filter and ensure that it is clean. And if you find it dirty, get it cleaned or replaced.

Problem 2: Chainsaw runs poorly

If you’re running the engine with a dirty or damaged spark plug for a long time, this issue is inevitable. You might also find a clogged fuel filter, or a malfunctioning carburetor existing in the chainsaw. 

A dull or damaged chain, inappropriate chain tension, or a misaligned bar also might affect your chainsaw to become operating worse than earlier.

These all parts having a bad situation are enough to force the chainsaw running poorly. At some stages, you’ll discover the engine is unable to run anymore. 

Before experiencing this kind of situation, I recommend you get a new engine.

How To Fix:

First, check the fuel filter and see if it’s neat or not. Found it dirty or clogged? You should clean or replace it. Next, check the spark plug and make sure that it is clean and properly connected or not. 

If the spark plug is dirty or damaged, replace it. Also, check the carburetor. If it’s dirty or malfunctioning, clean or rebuild it.

Problem 3: Carb issues

Noticed the saw bog down when you start to engage the wide-open throttle? This might end up with having carb issues with your Husqvarna 545. 

So, you’ll see the bog struggling to get turned off! It also occurs when your chainsaw is in need of a proper carb adjustment. 

How To Fix:

First, you need to clean the carburetor. Also, see if the fuel pump and mixture are in a good situation or not! 

You should replace the worn out gasket by consulting the owner’s manual for instructions. Try to remove any debris or foreign objects in the carburetor.

Problem 4: Leaking fuel

You might experience this issue due to a faulty fuel line. Also, having a troublesome fuel tank can make it happen. A damaged or worn out gasket is another reason. 

Over time, you might see the oil seal and oil pump remaining no more flawless due to lack of maintenance.

How To Fix:

A proper maintenance of the fuel line is required. Make sure that it’s not damaged or worn out. 

In the meantime, you’ll have the option to replace it anytime. But I recommend getting it replaced sooner if the physical structure is in a worse condition. 

Also, don’t go unnoticed by the fuel tank. Most trouble cases indicate that the tank is leaking after a while. 

Finally, check the gasket and make sure it’s completely sealed. If the gasket is damaged, replace it.

Problem 5: Autotune Starting Issue

Low fuel level is the key reason behind the incorrect auto-tuning. If the fuel level is too low, the chainsaw may not have enough fuel to start and run properly.

Dirty or faulty spark plug is another factor. You might have experienced the air filter getting clogged or dirty, right? Also, auto-tune gets affected due to the malfunctioning or dirty carburetor.

How To Fix:

It’s quite straightforward to fix this. I recommend getting a brand-new chainsaw and then setting the auto-tune by running this under partial load in a piece of wood. Also, operate this for at least 30-40 seconds. 

Eventually, you’ll notice a self-adjusting sound coming from the chainsaw. Once the chainsaw gets maximum running RPM, you’re all set!

Problem 6: Overheating Issue

A malfunctioning spark arrestor is a primary reason behind this. Also, if you find a clogged air filter existing here, you might find the chainsaw suddenly overheating in no time. Along with that, lack of lubrication is another factor here. 

How To Fix:

First of all, check the spark arrestor. If it’s clogged or damaged and not functioning properly, make sure to clean or replace it. Next, you have to clean the air filter if it has cached any dirt or debris. 

Finally, check the lubrication system and ensure that it is functioning properly. If the lubrication system is not working properly, refill the oil tank and adjust the oil flow rate as necessary.

Still, if you experience any of these problems even after solving in such ways mentioned here, I suggest you follow the owner’s manual for troubleshooting tips or reach out to a chainsaw expert!
