Chainsaws can be temperamental, and it’s the gas system that causes most problems. Saws, like all 2 stroke machines are finely tuned, any dirt or bad gas in the system can make them so frustrating to use.
Symptoms such as no starts, bogging, stalling, hot starting issues, surging and the list goes on. Bad gas is the root cause of many problems, the gas basically goes stale inside the saw and gum’s up the carburetor.
The solution is to remove the carburetor, clean and refuel. But often this won’t even work and you’ll need to replace the gaskets or the whole carburetor. You can avoid lots of these issues by simply using a gas stabilizer in the fuel system. I have a quality gas stabilizer listed below.
To use it, simply mix it with the gas/oil mix. You’ll note the gas stabilizer isn’t a replacement for 2 stroke oil. The stabilizer keeps your gas fresh and protects the fuel system from gumming.
On this page you’ll find useful tools and products I use when repairing and tuning a chainsaw.

Mix this with the gas when winterizing your small engine. Gas isn’t what it used to be, it goes stale, in some cases after just one month. Bad gas causes gumming and that’s a carburetor killer. Stabilizer will save you money and stress in the long run. Picture links to Amazon.com.
