The gap on a chainsaw spark plug should be 0.025 inches. This gap is important because it determines the size of the spark created when the saw is running. Improperly gapped spark plugs may not create sufficient sparks for the engine to get the proper power, or may create too large of a spark, resulting in the plug eventually “burning out”.
To ensure an optimal gap, a feeler gauge should be used to adjust the plug. To adjust the gap, use a curved tip tool to press down and spread the spark plug electrodes apart. One should take care to not forcefully and quickly separate the electrodes, as it could break the plug.
Using an improperly gapped spark plug can cause problems with your chainsaw’s performance, so it is important to make sure the gap is correct. Additionally, spark plugs should be generally changed out on a regular basis to ensure optimal performance.
What is the spark plug gap for a Stihl 025 chainsaw?
The spark plug gap for a Stihl 025 chainsaw should be 0.025” (0.6 mm). It is important to use the correct spark plug gap for your saw to ensure the engine runs correctly. The gap should be set using a feeler gauge; the electrodes should not be bent or filed.
Check the spark plug gap periodically and make any necessary adjustments before each use. Be sure to use the recommended spark plug type and gap size as outlined in the owner’s manual or parts list. Properly gapped spark plugs ensure the engine runs smoothly, efficiently, and with proper power.
What does MS stand for on Stihl chainsaws?
MS stands for “Multi-System” and is used to refer to the advanced technology of Stihl chainsaws. This system is composed of various components that work together to provide superior cutting performance.
The system includes components such as: a powerful engine, a low kickback chain, tool-less chain adjustment, Primer Bulb, and a Master Control Lever, along with a tip guard and triple-action guard. The Multi-System provides superior cutting performance by allowing the user to customize the settings to the type of wood they are cutting, such as soft wood, hard wood, green wood and knotty wood.
This customization allows for a more precise cut and improved safety. The system also makes it easier to use by allowing the user to adjust and monitor the chainsaw settings easily and quickly. The MS system also helps prolong the life of the chainsaw by providing superior quality and performance.
Why does my Stihl chainsaw leak oil when not in use?
It is normal for Stihl chainsaws to leak small amounts of oil when not in use. This is due to the design of the chainsaw, which includes an integral oil port leading directly to the handle and bar. When the chainsaw is turned off, pressure is no longer contained within the saw body, allowing some of the oil to escape out of the port.
This can result in visible oil leakage and dripping. To help minimize oil leakage when the chainsaw is not in use, you can fill the saw body with a high-quality bar and chain oil and then wipe down the bar, saw body, and exterior surfaces to ensure that any excess oil is removed.
Additionally, you can ensure that the saw’s oil port is firmly sealed to avoid any additional leakage.
What happens if you don’t gap spark plugs correctly?
If you don’t gap spark plugs correctly, then your engine won’t run properly. Spark plugs have a specific and very important job in helping your engine turn over and run, which is why it is important to gap them correctly.
Gapping is the process of selecting and installing a spark plug with the correct air gap; the air gap is the distance between the spark plug electrodes. If the air gap is too narrow, then the spark has difficulty breaking through the air/fuel mixture to ignite it.
This leads to a weak spark and poorer engine performance.
On the contrary, if the air gap is too wide, then the spark dissipates its energy before it can ignite the air/fuel mixture, which can cause a misfire. This can lead to serious engine issues, including a decrease in fuel economy and in some cases, engine damage.
Therefore, it is important to make sure that you gap your spark plugs correctly. It is best to consult your car’s owner’s manual or consult with a certified mechanic to ensure that you choose the correct air gap for your vehicle.
Should you adjust the gap on new spark plugs?
Yes, you should adjust the gap on new spark plugs when you install them. The spark gap is the distance between the center electrode and the ground electrode, and the proper gap should be specified in the engine manufacturer’s specifications.
If the gap on the spark plug is too wide, it will leave the spark plug unable to fire, and if the gap is too narrow, the spark plug might fire regularly but will not provide optimal performance. Adjusting the spark gap to the correct setting is also important because it helps ensure that the spark plug is able to deliver the right amount of power to the engine.
Some spark plug manufacturers provide gap gauges that you can use to set the gap correctly. However, if you don’t have a dedicated gap gauge, you can also use a feeler gauge to set the spark plug gap.
It’s important to note that if you take any measurements from the spark plug, be sure to use hand tools and do not use power tools to make adjustments as they can cause damage to the spark plug’s internal components.
What does pre gapped spark plugs mean?
Pre-gapped spark plugs are spark plugs that come with a pre-set gap size from the manufacturer. This means that the user does not have to measure and adjust the gap size before installing them, as the gap is already set and is suitable for the engine requirements.
Pre-gapped spark plugs can offer a range of benefits including improved performance, improved fuel economy, and improved engine longevity. Additionally, since the gap size is preset, installing pre-gapped spark plugs can reduce the time required for installation.
For these reasons, pre-gapped spark plugs are often used with modern engines, as it can provide a number of benefits that can help to improve the overall performance and functioning of the engine.
What years was the Stihl 025 made?
The Stihl 025 chainsaw was produced from 1992 to 2003. It was Stihl’s first mass-produced chainsaw and was available in two versions – one with a 1.4 horsepower engine, and one with a 1.7 horsepower engine. The 1.
4 horsepower model was made until 1999, when it was replaced by the 024 model. The 1.7 horsepower model was produced until 2003, when it was replaced by the MS 250. The 025 saw was an entry-level saw, intended for homeowners and casual users who wanted a chainsaw they could use for occasional light-duty work, such as light pruning and felling small trees.
The 025 was considered to be a reliable and durable saw, and was well-liked by users until its eventual discontinuation.
Do all Stihl products use the same spark plug?
No, Stihl products do not use the same spark plug. Each Stihl product model has a specific spark plug that must be used. It is important to check the owner’s manual for the correct model and year of your Stihl product to ensure that you are using the correct spark plug.
Using the wrong spark plug could lead to damage to the engine or even cause it to not run properly. Therefore, it is important to make sure you are using the right spark plug for your specific Stihl product.
