Never knew this motor had push rods and lifters... turns out my exhaust was so loos, push rod fell out. . flipped the motor and out she fell. re installed and adjusted both rockers as you have shown and voila!!! fired right up. Thank you for the great video!!
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.
Sweet! Great repair you did there, the only thing I'm curious about is that you did the valve adjustments by hand, no blade measures. Also what you said about leaving the exahaust valve slightly looser. Standard measure for intake and exhaust is 0.10 mm as far as I know. Very easy to check but I'd want to know more about what you think about the looser exhaust port settings as you see it.
I know what the factory measurement is. I do them by feel, not because I'm a hack, or lack knowledge, but because I have 45ish years of experience working on everything from modern, and vintage European cars (Porsche/BMW/MBZ/VW/Audi/Volvo/Saab) to all manner of power equipment, large and small, including generators, etc. Regarding your question about; why do I set exhaust valves a little on the loose side of spec? Exhaust valves live their life in the extremely hot blast of combustion gasses/flame. They are cooled only during the amount of time that they spend seated against the valve seat. The longer they rest against the seat, the more they cool off. The cooler the exhaust valve, the longer it/they live. The very slightly "looser" (wider) exhaust valve gap, allows that to occur. Additionally, the machines that I work on are all commercially used, which means they are in the hands of "workers" who don't care about them, and run the machines extremely hard. Happy exhaust valves help these machines live longer.
I use the dealers that selling parts on ebay, and www.diyparts.com has all of the factory parts diagrams online. Thanks for watching and for the kind words!
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!)

Thank you very much, making it Easy for us.
My pleasure! Thanks for watching and for the kind words!
Well done mate, many thanks ! Helps me out quite a bit 🙂
Glad it helped! Thanks for watching!
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.
This video should give you a hand: ruclips.net/video/7RnA4dUMpm0/видео.html
