Husqvarna Chainsaw 455 Rancher Troubleshooting: 3 Easy Solutions
Between Husqvarna and Stihl chainsaws, the former has more efficiency and durability. However, they aren’t flawless and thus create different problems sometimes.
To save you some time, we have categorized the problems and solutions.
1. Degraded Engine: Bad Airflow System
An engine requires good airflow to burn fuel. Improper combustion will ruin the engine’s efficiency.
Replace the Air Filter
The engine breathes air to burn fuel. Therefore a blockade caused by an air filter can ruin the combustion.
Check on the air filter and if it’s clogged, your best bet is to replace it.
Don’t worry, though. They are very cheap and easy to install. There are two screws; one at the upper side and the other at the bottom side.
First, unscrew the screws and take the dirty filter out. Then place the new air filter and re-screw them back.
2. Faulty Fuel System or Bad Oil Mix?
A poor fuel supply causes your engine to run rich or lean. Both conditions can wear out your engine and must be avoided.
Check On the Fuel Mix
First, you’d like to make sure your engine is running on the proper fuel mix. Also, if your saw has been unused for some time, it’s best to remove it completely.
Here’s a good mix of 2 stroke fuel –
- For a 50:1 ratio, 1 gallon of gasoline needs 2.6 fluid oz of oil
- For a 40:1 ratio, 1 gallon of gasoline needs 3.2 fluid oz of oil
Maintaining these ratios will keep your engine lubricated and increase efficiency.
Use a Fuel System Cleaner
Sometimes fuel tanks can get very dirty after a lot of usage. In that case, you can use a fuel system cleaner to get rid of any dirt or gunk.
Pour the fuel tank and let it work for a couple of hours. Then start the engine to distribute the cleaner evenly.
Examine the Fuel Line
There’s also a fuel line connected to the fuel tank. Pull the fuel line out just a little bit and see if there’s any crack or damage to it.
If you find any kind of crack or other physical damages, it must be replaced.
3. Bad Spark Plugs Cause Ignition Failure
Spark plugs are a key component in the spark system. Bad spark plugs may cause faulty ignition which is harmful to the engine.
Check and Replace the Spark Plugs
As we’ve already mentioned, spark plugs get worn out. This creates a gap between electrodes. So, we’ve to check the gap and other dirt issues before attempting to replace it.
To help you out, we’ve simplified the process for you –
- First, locate the spark plugs. It’s usually at the back of the engine. If you have the engine manual, you can easily get the information from it.
- Remove the spark plug and check whether it has dirt or carbon build-up. If it has some build-up, it must be sanded with 180-220 grit sandpaper. Also, if the spark has oil build-up or dirt, use a wired brush first.
- Don’t plug in the spark plug yet. Only attach the spark plug wire. Now touch the metal plug head with a metal surface and pull the cord.
- If you’re seeing sparks, then your spark system is fine. However, if the engine is still having difficulties starting up, follow us to the next step.
- Now we’re going to check the gaps. A spark plug needs to maintain a certain gap to create ignition. Too much gap means the electrodes fail to spark efficiently. On the other hand, a lesser gap means not enough air to incite an ignition.
- The gap gets enlarged over time due to spark plugs being worn out. If the gap seems too big, it’s time to replace the spark plugs.
Here are some recommendations from us regarding spark plugs –
This will help you pick whatever you like and get your engine started!
Replacing and installing a new spark plug is very affordable.
However, the same can’t be said about carburetors or bearings! Although, they rarely cause problems because of the 455 Rancher being a lightweight saw.
If these steps didn’t fix the engine, it’s likely that the carburetor is faulty or dirty. Opening and adjusting a carburetor needs precision and skills.
In this case, you can either buy a new carburetor or choose to fix it. The latter option does require a specialist, though. Don’t hesitate to hire a professional if these methods seem too complex to you.
