The mixing ratio using Stihl brand oil is 50:1 or 2.6 oz. oil per gallon of gas. Stilhl oil is recommended though a name brand oil for another air-cooled equipment brand could be substituted. Most are the same ratio.
The STIHL MS 260 chainsaw was introduced in the late 1990s, specifically around 1999. It was designed for professional users and featured a balanced design, making it suitable for various cutting tasks in forestry and landscaping. The MS 260 became popular for its reliability and performance in demanding conditions.
The Stihl MS 260 chainsaw has a displacement of 50.2 cc. This engine size provides a balance of power and weight, making it suitable for various cutting tasks, including firewood cutting and light to medium-duty tree work. Its efficient design and performance contribute to its popularity among users.
The Stihl 026 Pro has a 44mm X 32 MM bore and stroke 48.7 cc 2.96 c.i. with about 3.2 h.p. The Stihl MS 260 has a 44.7mm X 32 MM bore and stroke 50.2 cc 3.06 c.i. with about 3.2 h.p. The figures I have here I found on several different internet links. Hope this answers your question. Thanks. Bryan
only how the model number reads. In 2001 Stihl changed how there model numbers read. Previous to 2001 for example their models were such as: 026,044,046,064,066. Once they changed the model#'s they changed them to: MS260, MS440, MS460 etc.... Saws are still the same MS means: "Motor schlagen" or in German "Chainsaw" There IS A DIFFERENCE! the newer models that use the reversed numbers of the old Models (026 = 260 for examples) have the EPA carburators. This makes for a slightly less powerful/efficient saw.
The ratio of 240 to 260 can be simplified by dividing both numbers by their greatest common divisor, which is 20. Thus, 240 ÷ 20 = 12 and 260 ÷ 20 = 13, giving a simplified ratio of 12:13.
.025:1, gas to oil
In 2002 the MS260 replaced the (identical) model 026, which had been in production since 1988
It is 2 to 13.
A good 260/230 ratio for RNA quality assessment is typically around 2.0 to 2.2. This ratio indicates the purity of the RNA sample, with higher values suggesting better quality.
To find the model number on an 18-inch Poulan Pro 260 chainsaw, look for a label or sticker typically located on the side of the engine housing or near the handle. The model number is usually printed in a clear, readable format, often alongside the serial number. If you can't find it there, check the user manual or the bottom of the chainsaw for additional information.
A high 260/230 ratio in DNA analysis indicates that the DNA sample is pure and free from contaminants, which is important for accurate and reliable results in genetic testing and research.
The Stihl Ms261 is the replacement of the Stihl Ms260. The 260 has been on the market for many years and became outdated. Most important differences are the new designed so-called "2-mix" engine that is more fuel-efficient and evironmental friendly, and the better AV system on the 261. The new 261 is a bit more powerfull but due to the new av-system in which the engine is isolated from the handles also a bit heavier.
