this was donated to us after being thrown away, lets tear it apart and see what failed on this 4 stroke trimmer, how it works and if we can save it.

    I'm sure you know by now but there is a centrifugal clutch in there, need it for the cultivator and probably other attachments.

    what part of the country you live in, where people throw away / give for free lawnmowers, chainsaws, generators, snow blowers, tractors, excavators, airplanes and boats? i would like to move there..

    Stihl likes to make 4 stroke trimmers that still need mixed gas. My buddy has one that does. Kinda defeats like... Half the purpose, IMO.

    In my country, it is impossible to find such machine in a dump site. USA great place to be in this case. But, i don't fancy the cost of living there though. I'll be homeless with the kind of money i have. You guys over there, stay strong and well.

    Find out how the cable is driven in the center of the crankshaft. Fake that and extend it with a shaft beyond the pullstart. Then add a torque converter after the pullstart. I mean one of those CVT 2 pulley belt things. Put one such engine/gearbox assembly on either rear tire of a go-cart. Get 4 engines and you can have a four wheel drive go-cart!

    What if you cut the end of the shaft, pass the pull start. This way, you end-up with a covered driveshaft, machined at the length you want.

    Grind A Small Bolt or Shaft Square and Fit It into Where The Cable Goes.. You Can Tack It with A Little Weld or Some Really Strong Epoxy.. Then Mount A Little Sprocket or Belt Drive.. And Use It in A Scaled Model of "Some Vehicle".. And Get Some Servo's to Make A Cool RC Car Out of It.. I Bought A "LOT" of Weed Wackers..50 of Them, Various Models For $80 A Couple Years Ago... I Made Friction Bikes.. Models..A Little 15V Generator With A Motor And Automobile Blower Motor (But, Almost ALL DC Motors Will Produce Current When The Shaft Is Spun.. As You Prolly Already Know..Just For Those That May Not).. A Lot of Different Projects.. My Nephews Love Them... Great Little Learning Tools As Well.. By Taking Them Apart & Putting Them Back Together Gives A Great Opportunity For Young People To Learn How Engines Work On A Basic Level... I Also Used A Couple To Trim Grass ..Lol.

    I just repaired one of these trimmers that I had sitting around for 10 years after pulling it from the trash. Turns out the bolts holding the rocker bracket to the crank housing had backed out. I’m thinking they forgot the thread locker during manufacturing. Weird thing is that the compression gauge shows 60 psi, but it runs great.

It's hilarious how you were able to disassemble the valves with your fingers, man they really are so so tiny. It reminds me of the little RC engines, their super tiny as well, right! takes like 3/4 of a oz of oil..hahaha.

    So glad I came across this, I have been actually making it one of my little hobbies to actually find and resurrect lawn mowers that are just thrown out. There was one that gave me quite some trouble with adjusting the throttle Etc, but that's all I needed, a little bit of adjustment, a new spark plug and cleaning the flywheel and boom! I had literally a $600 lawn mower in my hands for some TLC

    Thing I learned about weed whackers and other similar two stroke stuff (and the small four strokes) , if the pull start is on the same side as the output shaft (like this one) it’s a “half crank” versus the ones where the pull start is on the opposite side - those have a full crankshaft that is supported on both ends like the larger engines, they are more expensive but they last much longer. There’s one of these micro four strokes that’s got an overhead cam with a tiny timing belt that runs it.

    If I'm not mistaken, the old one from the stash has a straight shaft, which is supposed to be stronger than the curved shaft of the one from the dump. The straight shaft one would probably be a better candidate for modding into something nifty.

    A few years ago: Snowblower, trimmer, whatever won’t start when I need it. Call service shop, haul machine over there and wait three weeks with the other Schmucks in the same position (while no yard work gets done and wife is “unhappy”), not to mention $150 out of pocket. Now: Snowblower, trimmer, whatever won’t won’t start and Dad gets that grin on his face - 30 minutes (or less) later, machine is running, work gets done, wife is happy. I owe it all to Mustie!! My father was a gifted mechanic, but he was killed when I was 8. Always had the aptitude, just didn’t have the knowledge. Mustie has given the knowledge and confidence to tear anything apart and know I have a really good shot at getting it running. There are no words of adequate thanks!!!

    The four stroke that uses premix is the Stihl 4mix engine, it’s done that way so there’s no separate oil reservoir to worry about and so that the same 50:1 premix can be used all across the line whether it’s 4 or 2 cycle.
