Stihl 024 Super Chainsaw Low Power Failure Diagnosis And Complete Tear Down! PART 1 

I really dont understand why I'm addicted to watching these videos of yall working on these saws but I am

I suspect many viewers wouldn’t know why you rotated the saw in all directions while running. It’s one way to detect leaking seals but I didn’t know it might reveal an intake leak due to faulty AV! Makes perfect sense now that I think about it, so thanks! Another diagnostic to add to my list! I’ve seen failed AV’s that have damaged other things though, like an impulse line connection at the port. THIS is why I spend so much time on RU-vid - to mostly learn diagnostics. THANKS, TYLER!

You’ll do the best checking that I’ve seen on utube and it’s easy to see why people are coming to your shop Extremely well done and you’ll know what you’re doing 😊😊😊 Thank You’ll ❤

024 are great little saws! worth saving.

My vacuum/pressure tool didn’t function properly when I first got it. Disassembled, cleaned, grease O-rings with silicone - problem solved. Hasn’t given me any problems since and that’s over two years. I found the original assembly to be dry - missing any kind of grease - which made it very difficult to pump with one hand. (Not the same mfr. as yours.)

I enjoyed watching you go through and diagnose this saw. Definitely rebuild that little Stihl, they are good units!

Nice old Stihl when they made real saws a new piston&rings bar & chain few parts and you have real runner for many seasons.

Since this saw was actually running in the beginning my first step after discovering that it stalled out in the downward orientation would be to spray a volatile with a straw at different specific locations while running the engine to pinpoint the leak. That’s quick and simple and would precede the more time-consuming step of doing the pressure/vacuum testing.

I’ve been fabricating my own block off plates as I need them. I made the tapered width ones to start but I was never happy with having to use a carb or muffler to hold them in place. Most so far are a thicker rubber into which I’ve drilled holes but now I’m starting to make them out of metal stiff enough to not flex. My latest one includes the metal plate with rubber scrap from membrane roofing glued permanently with one set of short screws. All kept in a ziploc bag as one complete set. I have a huge selection of harvested screws from which to choose in case these don’t fit future jobs. I suppose eventually I’ll have a complete set of blockoffs for most small engines. Your multi-hole plate is another solution but I’d prefer to have purpose built plates like mine.

The first place I always check when pressure testing with soapy water is my own testing connections. I fold over the line to confirm the joint at the tester is good and then go to the spark plug hole adapter I use to make sure the adapter and line connection are good. Then I check intake and exhaust. After that the seals. I’ll play around with vac versus pressure to see if the seals are wonky. If all else fails I’d immerse the whole thing in a bucket of water, although I haven’t had to do that yet. Just thought of something else - I check to make sure head screws are tight and spray all around the perimeter of the joint. Tyler struggled to locate the leak he was hearing. I would have used a piece of fuel hose as a stethoscope to pinpoint the leak at that point. I also would have rotated the engine to see if the leak or sound changed.

Cordless impact is much better to remove flywheel nut, no piston stop needed..

Thanks for this video. I’m working on the same saw at the moment, saw has a bog and feels hot to me. Is there a part 2 to this series?

The minute I saw that air filter I suspected that was the low power issue but I have to watch the rest before I know for sure. 😉

Maybe the twine is the stuff from chainsaw chaps? Man I can tell you have torn that type of chainsaw apart a few times. Obviously not your first rodeo on these saws.

Going by your experience as far as Stihl's, what oil for the gas mixture would you use. Some say Stihl oil is junk. Others I have watch choose Red Max

Unless you have some reason not to, I'd love to see you post your email in the channel description. There sometimes when I think off-channel communication may be more appropriate, at least for me.

How far is your shop from Trenton. I'm in the market for a new lawn tractor.

If you haven't looked into using an oscilloscope to look at the secondary waveform patterns of these engines, you should try it. If you had the oscilloscope setup it would only take a few seconds to turn it on and clamp the probe onto the spark plug wire and start the saw and the oscilloscope will give you a picture of the waveform pattern. You can see high and low compression and see rich and lean fuel and see other problems right away. Id imagine most small engines would have a very basic and easy waveform that is quick to learn. Heres a video of the guy explaining it ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-nRw4fIBZWzU.html

Always start the saw on the ground much safer way

Lol, "let other people use your tools", you better not name any names... I have a 024 that reliably dies when turned sideways, I really need to get around to fixing that one of these days.
