How big of a bar can I put on a 391 STIHL?

The size that you can fit on your 391 STIHL depends on the type of saw you have and what you specifically need it for. Generally, you can put a saw bar that is up to 20 or 24 inches long, although some models can take up to 28-inch bars.

It’s best to check your owner’s manual for the exact specifications for your saw to ensure that you get the right size. If you have a specific cutting purpose in mind, you should also research the ideal bar size for the task.

For instance, if you plan to cut large trees, you may want to opt for a larger bar of 28 inches or more, as this will help you power through the wood more quickly. If you plan to use your saw mainly for limbing, you may be able to get away with a smaller bar size of around 20 to 24 inches.

Can you put a bigger bar on a Stihl chainsaw?

Yes, you can put a bigger bar on a Stihl chainsaw if you wish to. Including the make and model of the chainsaw, the activity you plan to use it for, and the power and size of the engine. It is best to consult a certified Stihl specialist or a chain saw tech at a local professional chain saw dealer before purchasing a new bar.

If you choose to do it yourself, you must also select a bar that fits your chainsaw as many of the bars available are not interchangeable. You must also be sure to select a bar that is the proper length and gauge for the tasks you plan to use the saw for.

A longer bar requires more power and a thicker gauge greater wear resistance. Finally, when investing in a replacement bar, you must make sure to purchase one that includes a chainsaw chain which is balanced for the same size and brand of saw.

What’s the biggest bar you can put on a Stihl chainsaw?

The biggest bar by length that can be put on a Stihl chainsaw is 32”. However, depending on the model of the Stihl chainsaw, additional factors like the engine size and motor power can influence the bar size that can be used.

For example, while some Stihl chainsaws can accommodate a 32” bar, smaller engines or motors may not be strong enough to power such a large bar and require a smaller bar size. Additionally, bars longer than 32” are available, but are intended for use in professional timber operations and require additional features like compensating chains, guide systems and holder systems, which not all Stihl chainsaws have.

It is therefore important to check your Stihl chainsaw’s manual for the specifications of the specific saw you are using to determine the maximum bar length that can be safely used.

What Stihl chain cuts the fastest?

The Stihl chain that cuts the fastest depends on the type of wood and the hardness of the wood. Depending on the job, you may wish to choose a harder-cutting chain, like a full-chisel chain. These chains cut faster and are particularly useful for cutting faster in hard woods.

However, for softer wood, a semi-chisel chain may be the better option as these chains can stay sharp for longer, cutting at a slower speed but over a longer period of time. When selecting a Stihl chain, it’s important to consider the size, style and grade of the chain, to ensure you choose the most suitable one for the job.

Can I put an 18 bar on MS 170?

No, you should not put a 18 bar on a Stihl MS 170 chainsaw. The MS 170 has a maximum engine speed of 13,200rpm, and its recommended bar length is between 10-14 inches. By attaching a bar that is 18 inches long, the chainsaw will struggle to reach its maximum power and be operating outside of its specified parameters.

Additionally, using a bar that is too long can cause added vibration, affect the saw’s balance, and put extra stress on engine components, which can reduce the life of the saw and put the user at risk of injury.

Is a Stihl mini boss a 2 stroke or 4 stroke?

The Stihl Mini Boss is a 2 stroke engine. This type of engine is designed to fire once for every revolution of the crankshaft, resulting in a higher output than a 4 stroke engine. Stihl’s 2 stroke engines are also equipped with advanced technologies, such as their Advanced Cylinder Design, which reduces combustion noise and improves combustion efficiency.

This and other factors, such as their lightweight construction and higher power-to-weight ratio, make their 2 stroke engines a popular choice for lightweight, powerful and efficient gardening and landscaping equipment.

Is there a 4 stroke chainsaw?

Yes, there is a 4 stroke chainsaw available on the market. A 4 stroke chainsaw works in the same way as a traditional 2 stroke chainsaw, but it has a few key advantages. It produces less noise and vibration, is more fuel efficient, and requires fewer emission-intense components, making it a more environmentally friendly option.

Additionally, since it uses less fuel, a 4 stroke chainsaw is often cheaper to run and maintain in the long run. The engine of a 4 stroke chainsaw is typically larger and heavier than a 2 stroke model.

This could be a disadvantage for people who plan to use their saw for extended periods of time or in remote locations where they may have difficulty carrying the heavier machine.

How do I know if my chainsaw is 2-stroke or 4-stroke?

The best way to determine if your chainsaw is 2-stroke or 4-stroke is to read the manual for the model of chainsaw you have. The manual should provide information about whether the motor is a 2-stroke or 4-stroke.

Additionally, most 2-stroke and 4-stroke engines have distinct looks, with 4-strokes typically having a larger, flat cover over the cylinder and larger configurations. As a general rule, 4-stroke engines have bigger motors and more power than their 2-stroke counterparts, so if your chainsaw motor looks large and bulky then it’s likely a 4-stroke.

If the motor is covered and looks normal or slightly bulky, but still small then you likely have a 2-stroke engine. Finally, you can always contact the manufacturer of your chainsaw to determine if you have a 2-stroke or 4-stroke engine.

Which is better 2-stroke or 4-stroke chainsaw?

The answer to which is better – 2-stroke or 4-stroke chainsaw – is highly dependent on what you plan to do with the chainsaw and your own preferences.

A 2-stroke chainsaw has the advantage of being lighter and more maneuverable, as well as being less expensive to purchase. It also runs on a standard fuel mix and is typically easier to start and maintain.

2-stroke chainsaws are great for occasional use, general pruning, and most residential chores.

A 4-stroke chainsaw runs on regular gasoline, like a car, and is quieter. This type of chainsaw is also less smelly, has reduced exhaust emissions, and is better suited for more demanding or commercial uses such as felling larger trees, cutting firewood, or for long periods of use.

They are heavier and often more expensive than 2-stroke models, however.

Ultimately, the choice between a 2-stroke or 4-stroke chainsaw is more of a personal preference than an absolute right or wrong answer. The right choice depends on what you plan to do with it, how frequently you will use it, and your budget.

What does it mean to 4-stroke a chainsaw?

Four-stroking a chainsaw means to run the saw in an inefficient manner, which happens when you run the chainsaw too slowly and without a full throttle. This causes the cylinder to only complete two of its four stroke combustion cycle, resulting in the saw running ‘lean’, which reduces the power and makes the saw more likely to stall.

To 4-stroke a saw, the machine is run at low RPMs and without opening the throttle. This can be caused by having the wrong chainsaw bar oil or the wrong type of fuel being used. The machine would also need proper maintenance to ensure a sufficient amount of air circulation and an unobstructed fuel system.

To avoid 4-stroking, the chainsaw needs to be run at full throttle and adjusted for the proper fuel-air ratio to maximize power.

Are Husqvarna chainsaws 2 or 4-stroke?

Husqvarna chainsaws are generally designed as four-stroke engines as this has become the industry standard. The four-stroke system is much more efficient and produces fewer emissions, making it the preferred choice.

Two-stroke engines have a premixing relationship between fuel and oil, whereas the four-stroke system has a separate area to inject each. Operating on a four-stroke engine means there is less need to carry the container of engine oil due to the use of a crankcase to store it.

Additionally, the four-stroke engine is quieter and runs more smoothly for a more comfortable feel when in use. Most Husqvarna chainsaw models are four-stroke designs, providing an improved user experience and a low environmental cost.
