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 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.
.025:1, gas to oil
It is 2 to 13.
In 2002 the MS260 replaced the (identical) model 026, which had been in production since 1988
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 The 260 has been on the market for many years and became outdated.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.
The rear end gear ratio on a 1980 Oldsmobile is 3.73, in the overdrive gear. The low gear ratio is 1.43.
There are several things that can be done once DNA is purified. The first thing to do is to check its purity by measuring its 260 to 280 ratio. IN this method, the absorbency of the sample is measure at 260 and 280 nm. If the ratio of these two numbers is between 1.8 and 2.0, one can consider the DNA to be pure for further applications
