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
the 026 pro is a newer version
Myusual go-to site does not list any of the MS series units, but I can link you to the manual, if that will do.
The Stihl 036 Pro is 61.5cc with a 34mm stroke, 48mm bore, and makes 4.6 horsepower at 9500 rpm.
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.

A Poulan Pro chainsaw may keep flooding out due to issues such as a clogged carburetor, a faulty fuel line, or a malfunctioning primer bulb. When these components are not operating correctly, excess fuel can enter the engine and cause flooding. Regular maintenance and cleaning of these parts can help prevent the chainsaw from flooding out.
Poulan Pro Chainsaws are built in Ameeica, more specifically, the state of Georgia
