Stihl Chainsaw

[Scooby074]

I had a similar problem with my farm boss some time ago. I tried everthing you did and the stihl dealer told me to empty the gas, get some high test and use Stihl gas mix. It worked and I never had a problem again.

Good advice. I ONLY run supreme and the Husky Xp synthetic oil in my saws and never have a fuel related problem. (knock on wood)/

In the manual it will tell you to use high test 89 or higher. Your fuel mix should be 50:1. You may want to check your fuel lines. I know some folks that had issues and they turned out to be cracked or dried out fuel lines. I also agree with the post about the intank filter. You should also take your aircleaner off and air blow that out{this should be done quite often}. I WOULD NOT start adjusting things{carb}. If it ran before but dies now then something happened, chances are it is something simple. Start with the tank filter and tank line, air filter{this does pop in half for easy cleaning}, fuel lines going to the carb etc. Also make sure you have a good plug and the proper gas{important}. Once again I would NOT recommend going to a hotter plug, better to find the real problem instead of creating a new one{burned piston}. Keep us posted on how it is going

Keep the air filter clean, don't know how they PhotoShopped this.

You need to rebuild the carb. The needle valve is worn and excess fuel is pooling in the carb causing a flood condition. Carb rebuilds are easy on the 028. Just remove the carb and find the # from it. Your Stihl dealer will have a rebuild kit. Most are less than $10. Might also want to replace fuel lines since you have it apart.

Try turning the carb "L" screw in a bit to lean it up, less than 1/4 turn. If that makes it idle nice but too fast or slow, adjust "T" screw until it is at speed you want and below speed where chain will run (idle speed, screw affect butterfly closed/idle position).

If you are burning so much oil that the plug is carboned up, you might have excess carbon in the exhaust port. To examine and clean the port, remove the muffler. A clean exhaust port is important to smooth and consistent operation of a 2-cycle engine. Proper airflow is critical and restrictions of the exhaust port or muffler effects the performance. It might not be a problem, but if there is evidence of carbon in the cylinder, it's worth checking along with all the other good advice you've been given.
