[@billbannister9411]

A Very nice job thank you for posting it's a joy to watch

[@andreafilippo3298]

I'm always so amazed by your machining skills, Olli. Another nice workpiece

[@OlliKarhun]

Fantastic Olli...now a one flick starter..and it was so diffucult in the begin to get him run at all....but now....look at this!!!...awesome,!!

[@OlliKarhun]

You can say that again Peter! My hand is still hurting a bit :) Would do it again though, but hopefully learnt atleast something and don't have to :D

[@fiery1962]

Can’t beat the old long stroke engines.

[@Servoboy]

Wonderful and a very smooth runner. The Long Strokes are great, they have more of a 'buzz' than a 'scream' if that makes sense. Thanks for sharing this video

[@pirminkogleck4056]

super video my sparey casting and plan arrived today ! now i can start !

[@Preso58]

Nice work! Good compression and smooth action too. I'm currently building a Titan .60 glowplug engine with about 80% done so I can tell you've put in lots of work to get it running so well.

[@OlliKarhun]

Thanks Mark! I got interested about that Titan and found out you have a lot of vids abouy your build going on. Watched the number nine video a moment ago. Really liked your shop tour parts aswell and you showing a lot of extra ideas and solutions to many common workshop things. Great progress on the Titan and yes it really is a surpricingly lot of work to get these little things all lined up and neat and working. Keep up the good work and I am a new subscriber looking forward to your upcoming videos.

I have a new project in the works. Going to upload a video when I got time to make it 👍🏼

Erittäin komeeta settiä! ei moni pysty samaan

[@kerryjones1508]

Another fantastic video. Did it arrive as an engine kit for you to put together?

[@OlliKarhun]

Thank you Kerry. It kind of did as the castings did come to me pre made by a colleague. All the machining was done by me. Cast parts can be seen in the picture at 4:08 - 4:10

[@compact832]

Can you tell me how you ets the cilinder,is it beter /easier than paint? Nice video!

[@OlliKarhun]

I did heat it up and quenched in to the oil bath.

[@TrendNipper]

I'm studying engines for some time now, and intent to build a model one in the future, but there is one thing that I don't get: how the journal bearing gets lubricated when running without a oil pump and crank channels? In this type of environment the only thing I can imagine is some kind of oil fog during the intake getting into the narrow space.

[@CATech1138]

the pressure changes in the case during the piston stroke pump a small amount of oil through the crank journal...

[@TrendNipper]

@@CATech1138 Amazing, thank you for the information

I have had trouble finding Jef lemmens contact info . Trying to get nova 1 castings. I know this is a long shot. Any help is appreciated. Great video.

Bro how is work

[@cytron8787]

Hi, nice engine, do you need a special fuel for starting this type of engine or just diesel ? Thank you.

[@OlliKarhun]

Normal model diesel engine fuel. I use at the moment 38% kerosene, 34% ether and 28% castor oil with a pinch of IPN. Back in the forties the original designer of this engine used: ’24 parts petroleum, 24 parts turpentine, 24 parts paraffin oil, 15 parts motor oil and 13 parts sulfur ether. This mixture was used, among other things, for the Swiss diesel engine Dyno 1. ’

[@cytron8787]

@@OlliKarhun Nice, thank you for the info, I search for it ,really hard fuel to find .

[@balfasladicra5270]

hey im planning to make one do you think its gonna work without a spark plug and a valve spring

[@OlliKarhun]

Yes it surely does.
