Do chainsaws have reed valves? Most chainsaws, especially those that are considered high- end versions, do indeed have reed valves. If you are a fairly new to using chainsaws, you might not even fully realise what exactly a reed valve is. Basically, it is a piece of equipment that is sometimes found on high-performance 2-stroke engines that control the fuel-air mixture going to the carburettor. Of course, not every chainsaw is designed in this fashion but a lot of them are. This is important to know because if you have a chainsaw that isn’t performing well, it just might be because there is a problem with the reed valve and not with the carburettor itself.
Just as in any case with a piece of equipment, you have to know how your equipment functions in order to be able to successfully diagnose any potential problems. Chainsaws are notorious for being difficult to start and in some cases, they can be notorious for refusing to keep going even after you do manage to get them started. You would be doing yourself a favour to know ahead of time whether or not your chainsaw operates with a reed valve so that you can be better educated when it comes to diagnosing problems. The truth is, a lot of people think that they are having a problem with the carburettor or that the entire chainsaw is completely shot when all that really needs to happen is to replace the reed valve.
The reason that so many chainsaws have these small pieces of equipment is to allow them to perform with superior operation. For the most part, this works exactly as it is designed to work. The chainsaw performs well, you get more bang for your buck, so to speak, and the chainsaw is capable of cutting just about anything that you need to handle around the house. If you are using a high-performance chainsaw that is designed for more severe use, you almost certainly have a reed valve. As long as it operates the way it was designed to function, the chainsaw typically operates better than one that isn’t designed with a reed valve in the first place. With that being said, having a chainsaw with a reed valve that isn’t operating properly can make you lose your sanity if it goes on long enough.
If you do notice that the carburettor isn’t performing as well as it used to, the chainsaw itself isn’t running as smoothly, or it simply doesn’t want to start, this is usually a good place to start looking for trouble. More often than not, a chainsaw that is equipped with a reed valve can have its performance restored by simply replacing it. Obviously, if that fails to solve the problem then you will have to move on to other things such as looking at the operation of the carburettor itself. In reality, trying to troubleshoot problems can be a process of elimination, so it always makes sense to start with the smallest and least costly piece of equipment before looking into more complicated matters.
