Chainsaws are powerful tools that can be used to cut through just about anything. But when they get stuck or stall, you may not know what to do next. If your chainsaw keeps stalling then there are a few things that might be the cause of the problem.
Chainsaws are necessary tools that allow you to clear out fallen trees, branches and other debris that can be blocking your way into your home or just making it difficult to get around. However, if your chainsaw keeps stalling unexpectedly, there is usually an underlying issue and you may need to take a closer look at the equipment.
Stale gas in the tank can lead to engine failure as it causes buildup on valves and rings. Air leaks from fuel system hoses will also result in a loss of power due to an incomplete combustion process. A dirty air cleaner screen or clogged carburetor will also cause engine stalling which could require costly repairs.
The good news is these problems are easily fixable with some basic maintenance tips!
How do you fix a chainsaw that won’t stay running?
Chainsaws are a necessary tool for many people. It can be a frustrating experience to find your chainsaw won’t stay running. What causes this? Is it fixable or should you just buy a new one? It may not always be an easy answer, but with a little troubleshooting and some help from the internet, you should be able to figure out what is wrong and how to fix it.
Whether you’re a lumberjack, farmer, or homeowner who needs to cut down trees and clean up fallen branches after storms, chainsaws can help you get the job done faster. But what do you do when your saw won’t stay running?
The most common reason chainsaws won’t stay running is because of fuel problems. Gasoline-powered saws will often cut out due to low fuel or an empty tank. There are some simple steps you can take to remedy this problem and get the chainsaw working again quickly.
Why does my chainsaw die at full throttle?
When your chainsaw engine dies at full throttle, for expert help with identifying the right part to stop this from happening again refer to the user manual. A general repair guide for other models of saws can usually be found in the manual or online.
Here are 4 quick pointers to identify where any potential issues might lie:
- The carburetor system (bad gas),
- Fuel lines or filter (dirty gas line or clogged fuel filter),
- Air intake valve (dirty/clogged),
- Muffler (wet from overuse)
Your carburetor plays a crucial role in the function of your chainsaw. When it becomes clogged, you may need to have someone rebuild or replace it for you before using it again.
The carburetor is the part of your chainsaw that mixes fuel and air in the correct ratio so combustion can occur. When it becomes clogged, due to old gas sitting inside over time or other reasons like corrosion, this task will not be done effectively which when you run on full throttle may result in damage.
Cleaning and rebuilding the carburetor instead of replacing it might fix things at first but if internal components are damaged then replacing it may be necessary.
Fuel lines or filter
When it comes to protecting your chainsaw, you should know that there are two main purposes for the air filter and fuel filter.
The first is preventing dirt from reaching the engine’s intake valves or being inhaled by users; this can help prevent damage due to gritty debris entering delicate parts of a machine.
Similarly, an improperly filtered gasoline stream could be damaging if not filtered out before getting into contact with sensitive components like injectors. These would create a clog which might result in bad performance at idle but more importantly will eventually cause the permanent failure of those important pieces during full-throttle operation. This is also one of the reasons why many people recommend using top-quality filters.
Air intake valve
Air filters in chainsaws are incredibly important for protecting the engine from dirt and debris. You need to clean them often, otherwise, you risk a clog that will keep your chainsaw from operating at top efficiency.
If it becomes clogged, you will not get enough power to operate at full throttle. Fortunately, replacing your dirty old air filter with a new one is an easy job – all that needs doing is locating the carburetor on top of which it resides and removing the clog by gently blowing into or shaking out its contents.
Carbon buildup is a major issue with chainsaws. The exhaust port, muffler or spark arrestor can become clogged and the engine will die out when gasses cannot exit in the form of an exhaust stream.
When this happens you will notice that your chainsaw will stall quickly after its original speed slows down from full throttle.
Clogged exhaust ports and mufflers can cause your chainsaw to die. Make sure that you know the difference between a clog in one of these parts or engine, by checking for visible carbon buildup on any part before replacing it.
Tuning Your Chainsaw
A tune-up procedure is a must for your chainsaw to stay running well. Cleaning the filters and adjusting the carburetor, as part of this process, is necessary to keep it going smoothly with less maintenance down the line.
A tune-up should also include inspection of spark plugs and replacing them if needed.
