The carburettor is an essential component in engines that determines its performance. Though it is also true that a poorly maintained carburettor results in plenty of engine problems. Whether you’re a professional or a gardening enthusiast, it is always crucial to count on trusted chainsaw carburettor brands like Stihl carburettor and at the same time also know how it works so you can get the most out of it while avoiding breakdowns. This post gives you a brief description of the working of a chainsaw Stihl carburettor and appropriate methods to keep it in proper working order.

How Does A Stihl Chainsaw Carburettor Works?

The carburettorof chainsaws consists of a venturi duct that helps in accessing the flow of fuel from jets by creating a vacuum. The air or fuel is then sent to the engine and regulated with the help of a throttle valve. In general chainsaw parts suppliers provide a carburettor that comes with flexible screws to control the flow of the fuel in the jets.

By adjusting the screws, the engine RPMs can easily be controlled. Aside adjustment, a chainsaw carburettor should also be maintained by regular checking its components and replacing its damaged parts and timely cleaning of jets.

Importance Of Adjusting Stihl CarburettorOn A Chainsaw

To adjust the chainsaw’s carburettor, you need to ensure that both the screws, i.e. low-speed (L) and high-speed (H) are adjusted properly to obtain an optimal setting of the engine RPMs and its functions.

Generally, a chainsaw Stihl carburettor has three key screws, namely, low speed, idle screw, and high speed one. Each of these screws controls the amount of fuel entering the engine at low speed, idle or high-speed.

The main purpose of screw adjustment is to control the fuel flow to the engine. For instance, if a screw is loosened, it allows fuel to mix with air, thus making the mixture of fuel and air rich. It leads to lower RPMs. Whereas, if the screw is tightened, it restricts the flow of fuel and makes the mixture lean and revives the engine. Tightening the screw, on the other hand, increases the RPMs, and loosening them causes them to fall.

The appropriate adjustment of a chainsaw carburettor is an integral part of the regular maintenance of any chainsaw model like Stihl or Husqvarna. It is important to know the proper functioning and maintenance of carburettur to get the most out of it and extend its lifetime.
