I have rebuilt a few two strokes, something I do is soak the muffler, completely submerged in a container of diesel over night. Then after draining it I burn off the remaining diesel and oil residue inside. It cleans them out like a treat giving improved flow.
Very interesting re-build. Fairly certain I would have been stumped with the oil in the bottom end. Also all the bearings here are either needle or roller ball bearings. Something a 4 stroke engine rarely come with. This should give good long life. Also, not sure if you plan to use it as a power plant for a lawn mower, but a 2 stroke runs at a higher rpm and also gets double the power strokes of a 4 stroke motor, making it a step ahead on a 4 stroke. Oil burning is what killed this idea for the USA and I think the EU geography also. But in spite of this, I like the idea. How much fuel does a lawn mower actually use over it's life anyway?? certainly less than a week of use on an automobile.
>2 stroke runs at a higher rpm and also gets double the power strokes of a 4 stroke motor, making it a step ahead on a 4 stroke Double the power strokes doesn't mean two strokes have a leg up. Two stroke engines are grossly inefficient, the Robin EC10 being a prime example. There is a direct drive and a reduction drive model for 4,000 or 1,600 RPM operation and both put out a maximum of 3 hp for continuous operation. A four stroke engine of similar displacement of around 100CC is from 6-20 HP. The only type of four stroke engines it'd have a leg up on are old L head or T head engines. >but a 2 stroke runs at a higher rpm Barely. A small four stroke is in the 3,600-3,800 range, the EC10 is 4,000. Two strokes sound a lot faster than they are because of the 2x number of power strokes.
I also agree. Unusual to see oiled bottom end on a 2 stroke. I do like it however, as I think this makes for a much more robust and long life engine, something that 2 strokes are NOT well known for.
Great restoration - looks amazing and it seems to work well too! Is it just me or does the engine look roughly the same shape as a toilet? Maybe the manufacturer had a sense humor? Either way, great video! 👍
Nice job! I have to admit, in 40 years of working on engines of all types, this is the first 2 cycle I've seen with an oil sump. Thanks for the video!
It is quite unique I have to admit!

That is a good idea!
Great job on the engine, it looks good on that old mower deck.
Looks like it cranked very easy and sounds good too. Nice project. Thumbs Up!
Amazing job on this restoration! Love the sound of it!
Thank you very much!
That's a good sounding little 2 stroke. Great job. 😁👍
Great job! Robins are great little motors and easy to work on.
1:55 now you can use your lawnmower as a barbecue grill.
Nice work mate! Glad to see this one finally running!!
Nice job. It runs very well. :)
Now that looks like an engine i would modify and install on a custom 3 weeler trike.
Excellent job bro.
I like your methods in painting that was cool and nice restoration
Thank you so much 😀
Good video,as usual.bringing back to life to carry on for more years to come.keep up what your doing.👍👍👍😎😎😎
That's the plan!
Nice job on registration a vintage lawn mower engine
Sounds like a mini trail bike or a big chainsaw. Nicely done!
It does!

Came out really well :)
Thank you so much!
Outstanding restoration, well done 👍
Glad you like it!👍
You put the piston on backwards. You should fix it ASAP or the rings will destroy the exhaust port!
so beautiful, thank you.
Interesting… a piston-ported 2-stroke with oil in bottom end. Was this common? I’ve never worked on a Robin before.
Very cool restoration, by the way!
I don't think its all that common, I think the Yamaha MT110 also has a oiled bottom end.
You are right. The Yamaha MT110 also has oil in.

I like video👍
Jis maar hy klink lekker Andre.😁😁👍👍
Baie dankie man haha
Absolutely brilliant ☺️☺️☺️
Комментарий в поддержку канала и ролика, а также труда мастера.
Next video,please restore the body of the machine, and it’s color should be red or complete white.
The chassis was just for the test. The motor is now in my display unit.
Grandiosissima restauração 👏👏👏 sucesso a você 👍👍👍🇧🇷
Is that a ring forceps? LOL!
Cool 😎
That engine was a perfect fit for that classic mower 😎👌👍
Good morning from Southeast South Dakota. If you were close enough. I would like to have a 1957 boat motor rebuilt.
I would love to do that. Too bad I am so far away!

It does have a odd shape actually hahaha
Well, can't you pour more cleaning fluid ?? poured two drops and that's it ...
R20 for a litet of petrol in south Africa
I really do enjoy all your restorations. I do have a question, 'Where do you find all that you restore?'
Most of it I find either at the metal recycling yard or Facebook Marketplace.
Ai A. J. Dit is weer een van jou pragtige werke jy is n boffin
Baie dankie Tom, ek wardeer!
Do you pre start the engine 🤔 and make adjustments?
No that was the first start.
Pretty good job, but those taper-head , flat-head screws attaching the recoil unit look awful! there is no way those are original.🤨
I like them, they are copper and I like the color it gave to the project. Not original, not the ideal screws to hold the recoil unit, but i like them.
Did you use dynamometric wrench?
No.
Excelente muito bom !
Maravilha AJ! Gratidão

waar is die coilwire grommet dan?
Hy het nooit een gehaad nie, ek kon ook nie stock erens kry nie.
Parte is skaars. Ek soek nou n coil vir myne. Dit bly saam met die Yamaha MT110 die beste 2 stroke masjiene
You live in a very noisy neighbourhood 🤔
Its not always noisy, Mostly I make the noise hahahaha
