Choosing a used chainsaw? Sometimes it not even worthwhile to buy a second hand chainsaw depending on the size of saw ? Because a chainsaw has a 2 cycle engine (2 stroke) this means that they tend to wear out a lot quicker than a 4 stroke engine and also need a lot more care to maintain. The 2 main points when considering buying 2nd hand are make sure that it hasn't been over heated due to inadequate chainsaw 2 stroke oil that you mix with gas this lubricates the engine lack of oil will course over heating and might lock up the engine. Cleaning chainsaw air filter is also a must to stop contaminates getting into the bore and causing a lack in compression.
