Very impressive work Tom. I'd have scrapped the piston without question but you showed there is an alternative. Good example of cold seizing so thanks for sharing.

[@VintageEngineRepairs]

You’re very welcome! Thanks for watching :)

[@TomDobyMowerRepair]

you've inspired me to find some down time to clear out a whole building full of these machines and experiment!

[@VintageEngineRepairs]

Fantastic :)

[@budgillett9627]

Always! Enjoy your videos!

[@VintageEngineRepairs]

Thanks Bud!

[@almclean4835]

A very informative video Tom, nice one

[@VintageEngineRepairs]

Thanks Al!

[@TheGreasyShopRag]

I enjoyed that video. You earned a new subscriber!

[@VintageEngineRepairs]

Hey! That’s great, I’m a big fan of your channel :) I’m always watching and looking forward to the new content. Nice to connect with you in a message :)

[@jgray8879]

You’ve just given me hope 😁

[@VintageEngineRepairs]

Haha good to know :)

[@KensSmallEngineRepair]

Great vid Tom, I always replace the piston and rings though, especially if it an expensive unit like a Stihl or Echo. A junkyard no name, re-use like you did. Cheers!

[@VintageEngineRepairs]

Good call Kenny, if it was my own equipment and I could save it I would. For a customer I’d either recommend oem or good AM like meteor piston and caber rings.

[@sluggonotnancy6178]

Very good video. My son just seized up my 20 year old Stihl HL 45 hedge trimmer that worked perfectly for me for a long time. Now I'm trying to decide what to do with it. Good job.

[@VintageEngineRepairs]

Thanks for watching :) glad it was helpful!

[@tinkeringtaylor3053]

good video Tom well done 👍

[@VintageEngineRepairs]

Thanks Nev!

[@budgillett9627]

Greetings from Nebraska USA. 10:15AM here. 😁

[@VintageEngineRepairs]

👍👍

[@steveriggenbach90]

Great information. I take a lot of attention to the ring groove(s). Why not clean the cylinder with paper and a hone? Take care

[@VintageEngineRepairs]

Great question, the abrasive can bed itself in to the soft piston and cause more problems down the line. Best done wjth a file, then a used and worn bit of scotchbrite you’ve washed a number of times!

[@GuysPlayingWithTools]

Good vid mate. I can only get about $50 for a curved shaft, so if they are burned up they turn into parts pdq here

[@VintageEngineRepairs]

Spot on mate, same here, this was a one off for a video haha.

[@GuysPlayingWithTools]

@Vintage Engine Repairs I do that too. I get equipment more for videos than profit all the time.

[@haneyoakie14]

@@VintageEngineRepairsi appreciate both of you placing educational videos ahead of $$. I learn a lot from both of you. I usually have more time than money.

[@williamemerson1799]

Great! 👍🍺Not that I've ever straight gassed my Stihl MS180.🙄

[@VintageEngineRepairs]

Haha 😂

[@Jjay-tw1yy]

i’m wondering how to tune a carb on a trimmer that’s already out of adjustment where it won’t start

[@VintageEngineRepairs]

I’d look it over, it’s likely got old diaphragms inside the carb, the fuel line may be damaged, filter blocked etc. Once you’ve checked all that then set it to 1&1/4 turns on each screw .

[@Jjay-tw1yy]

@@VintageEngineRepairs thanks it’s a pretty new trimmer and supposedly someone ran the wrong gas in it i tore it apart and everything looks fine i got it to run fine and warmed up then once i shut it off it wouldn’t start back

[@PopaAlexandru.]

The cylinder can be polished, but the piston also acts as a valve. With scratches, how will it close properly? I always choose to change the piston in these situations. But only at 2T, at 4T is it sufficiently cleaned and the segments changed - that's how I proceed. ​

[@VintageEngineRepairs]

Works just fine, you wouldn’t do this with a race engine though.

[@niceguyhector]

Would this also apply to a dirt bike

[@VintageEngineRepairs]

It would, but a dirt bike is designed for maximum power, therefore I’d personally rebuild the top end fully. A weed eater or chainsaw just needs to function, unlike a bike that needs to be at its max capacity :)

[@Big_Johns]

Nice video Tom, I'll try this on a junker next season and see how it does. What does your shirt say? 🤣

[@VintageEngineRepairs]

Thanks Big John! It’s useful to know, even if you only use it occasionally :) Bahah, “dear Santa I want it all - a 3d television, a mute button for my wife and a fridge full of beer” LOL

[@Big_Johns]

🤣👍🏼🤣

[@raymondthompson4222]

Great job. Stihl 55 weed eater which # to adjust the H speed 10000rpm or 8400rpm

[@VintageEngineRepairs]

8700 - 10300 is manual recommended. I suggest starting rich and cutting with it. Lean the H until it just stops 4 stroking under the load of the grass.

[@raymondthompson4222]

Thanks much

[@Sensei948]

OIL MIX 33:1 IS GOOD ?

[@davidmann4533]

Use a ball hone

[@VintageEngineRepairs]

Na not on Nikasil, it leaves too coarse of an edge and wears the rings way too much

[@DicksSmallEngines]

& that my friends is how it’s done ! Laavvvlllyyyyy ! Take care 👍🏻🔧

[@VintageEngineRepairs]

You too! Thanks for watching!

[@James-dt7ky]

A reference to the "Frenzy" movie? Laavvvlllyyyy.
