How To Repair A Stihl 4Mix FS90 FS100 FS110 KM90R KM110R KM111R KM131R HT101 HT103

This video shows how to diagnose and repair a Stihl 4Mix machine that won't start after being left with ethanol based fuel in the carburetor for over a year.
Fuel related issues can be avoided by using Echo's premixed "Power Fuel" or simply treating your fuel with SeaFoam.

This is gold. Trimmer would not start. Newer than the one in the video. Bulb was clear and no cracks. Took it off and sprayed the ports (check valves) inside the bulb - like your example. Reassembled, and two pulls later it was running. Thanks PS I will do the other stuff later right now I have trimming to do.

That's awesome!! So glad you got it running again. If you'll only use Echo Red Armor, pre-mixed fuel, with no ethanol, you won't have any further fuel related issues. Don't use the Stihl Motomix in it, or the carburetor will be destroyed inside.

Very useful many thanks! My KM100 combi motor was struggling to start. I changed spark plug, air filter and fuel filter and now starts first time and smells different (like new!)

I was hoping it wouldn't start so we could see how to clean the carbureter. Any videos on that? Great video by the way.
