Part 1( • Stihl MS290 Rebuild: M... ): In this video I start the tear down process. I break down the chainsaw down to the piston to discover that internal engine damage has occurred. The piston is severely damaged.
Part 2( • Stihl MS290 Rebuild: M... ): In this video I complete the remainder of the engine tear down. I find additional components damaged and the culprit of the engine failure. I make a list of what is required to rebuild and place my order.
Part 3( • Stihl MS290 Rebuild: M... ): In this video I install the new complete engine assembly. During assembly I encounter a few minor issues. To finish it off I fire up this newly rebuilt chainsaw!

Oooofff dang that's tight.

[@yogibeer9319]

Awesome video! I always have to take pictures as I’m disassembling things cause if I don’t after I reassemble it I’ll end up with “I wonder what this is?” screws laying there. 😂

[@ThriftyGarage]

I like your name!

[@yogibeer9319]

@@ThriftyGarage Thanks, beer is my food pyramid😂

[@yodalmcfloodel6407]

Never understood why people don't just pull the saw off the bar when they get it stuck in a tree. It's a lot better than dropping a tree on it.

[@RG-wy1ol]

Thanks for making this video 👍🏽

[@ThriftyGarage]

I’m glad you enjoyed it!

[@bowlweevil4161]

before you pull it apart, take off carb cover, clutch cover, and chain and bar and use hi perssure air to blow all the dirt and chips out from all around the engine, helps to keep from getting all that crap all over bench and in engine when you pull cylinder off, good vid THANX

[@ThriftyGarage]

Thanks for the words of wisdom!

[@TheCrittercam001]

First time doing a top end rebuild and you did good buddy.

[@johnkuykendall7028]

I too broke the bit off on the same bolt.

[@ThriftyGarage]

That’s got to be a coincidence!

[@tysauce1986]

So I bought the same kit you did off amazon. I also noticed the decomp valve was malfunctioning on the first start up. So I replaced it with a hyway decomp valve. I noticed it really seemed to lack power for what I thought it should have been making. Did you respond seem to wake up after a few tanks of gas? Any idea what kind of rpms you were turning?

[@ThriftyGarage]

I’d cap the decomp valve. Mine gave me issues. Power was never an issue. I got a motorcycle clamp style rpm gauge and set it at 13 or 14,000 rpm. Whatever is recommended by the factory.

[@KCCLBTHORX]

I'm curious do you have the rebuild kit parts numbers. There are a lot of junk kits out there

[@ThriftyGarage]

There is an Amazon link in the description. Btw, I'm not saying this isn't a junk kit. It is rumored the quality control isn't as good as Stihl. But for 20% the cost and the ability to breathe new life into a damaged saw it was worth the risk for me. Check out our more recent videos on this chainsaw. Aside from the decompression valve failure this has been an excellent repair. If I were to do it again I'd plug the decomp valve.

[@emildumitrof9455]

Hi, can you please drop a link for engine, the site you bought it from. 🤝

[@ThriftyGarage]

Link is in the video description. You can also search "Carbhub 49mm Cylinder Piston Assembly for Stihl MS390" on Amazon.

[@chrisstokley7687]

just removed it kinda backwards! need remove the very end screw /that allows the black handle part to lift! then can snap -out the throttle linkage /remove the carb ,,then push the carb lines through the orange cover.!

[@ThriftyGarage]

Yea, everytime I take this apart I fell like I discover a better way going back together. Problem is by the time I take it apart again I forget which way was best. 🤦

[@pickleberryyum404]

I got that same drill. How u likeing it?

[@pickleberryyum404]

Lol. Btw that makita took those torx screws out on the bottom no problem

[@ThriftyGarage]

Makita for the WIN! I was actually looking at my growing cordless tool collection today and it's starting to get pretty big. Once you pick a battery platform it's hard to change. Plus the tools are so versatile I seem to keep adding without regrets. Now I can't imagine life without them. 🤣

[@hswing11]

watch Cheap Homesteading for moe detailed video...

[@ThriftyGarage]

Nature's Cadence Farm is also a helpful video as I mentioned at 4:30.

[@JBLOVEAB]

Loc-tite

[@bufford14]

I'm doing the same thing on my 290, I've got it going back to getting the carb back on and all the hookups. I didn't take any pictures as you did, I will do this next time for sure. If you have any pictures of this process would you be so kind as to send them to my email address? If you will please let me know and I'll send you my email address. Thanks a bunch.

What possesses people to believe they are being help, or that people want to view fast forward garbage. Slow it down, and explain what the hell you are doing each step of the way.

[@ThriftyGarage]

I already have a three part series tearing down the 290 and upgrading to the 390. I decided to do a different format video for this one so they weren’t identical.

[@Talachachannel]

Goofy 🤪 job

[@ThriftyGarage]

Thanks… I think…
