    I forgot to like it when it came out, but I made amends now. Such a great project to see, from Viipuri of the "golden age", a decade full of hope and progress in Finnish history (until it soured)

    I think you should use breaker points with a 1988 Ford Thick Film Ignition module of the minivan-remote-from-distributor-on-a-heatsink kind. When used with it's matching coil it can supply a V8 with sparks to 5000rpm. Best of all is somehow it calculates the proper "on" time for it's coil before every spark. It also shuts off after one second of no rotation. Marvelous piece of old tech nearly as hot as GM HEI which everyone know is a PITA but has a strong spark.

      It seems hardly any time ago that I was advising you on choosing a small lathe, and then later encouraging you to have a go at making your own castings! You have come a very long way in that relatively short time. You must be very pleased and proud of your achievements.

      @@kencroft7933Indeed! I looked back and checked, it was about 3,5 years ago 😁 Now nine engines later I am definately very happy how things have gone so far. I also realize I am still very new to machining but really looking forward to the upcoming projects and challenges. I have received a lot of help from people like you and many others along the way. That is the best part. Much appreciated 🙏🏻

    "Know what I like about this engine? It was built solid; And? That is what is needed. No plastic fittings for fluid fuel corrosion due to tolerance of material. However? I would like you to install a spring crank around the shaft area near the spinner for easy start. Overall? The item is good." 👍

    Ei tähän voi muuta sanoa kuin että teet hienoa työtä! Luin jo pienenä poikana Rolssi-jutun Tekniikan Maailmasta, se teki minuun suuren vaikutuksen. Minulta tällaiset jäävät rakentamatta, mutta onneksi sain nähdä ja kuulla Rolssin käyvän edes muiden rakentamana.

    It's listed as a 4 stroke; does it have an oil system or is oil mixed with the gas for lubrication?

    • @OlliKarhun
      @OlliKarhun  5 місяців тому +2

      @tenlittleindians it has 2% of synthetic oil mixed in the fuel and 15ml of motoroil inside the crankcase for splash lubrication.

    I watched your video about making the Nova-1 4.5cc engine, everything was cool, I really liked the video.
    Please tell me what material the piston is made of? made of the same material as the cylinder?

    • @OlliKarhun
      @OlliKarhun  9 місяців тому +1

      The piston of the Nova-1 is made of cast iron and lapped to fit. The cylinder is 42CrMo4 as is the cylinder sleeve on this one. This article describes the process of making the piston / cylinder fit exactly, highly recommended: www.adriansmodelaeroengines.com/catalog/main.php?cat_id=178

      Yes, this method of casting is quite simple, the components of the molding mixture can be bought in any construction store, and at the same time it is possible to obtain castings of complex shapes with this method.
