What an amazing little engine. I bought an m12, however it was faulty. I sent it back and enginediy sent me a m16, with a little camshaft tuning and proper engine knowledge, the engine runs FANTASTIC! I have never had such a reliable running engine before. With enginediy’s tremendous customer service, they got me an amazing running model. Starts up every single time, I’ve put around 13-15 hours of run time on it, and a lot of fuel through it, I’ve fully disassembled it twice, it’s a solid runner. If you are somewhat mechanically inclined, this is the ENGINE FOR YOU!
(Ps, I tried painting engine white, I did not prepare pint well enough, however removal was easy. Now back to normal.)
Forget my other review. I had a defective carburetor on my engine, within 12 days, engine diy send me a new carburetor and ignition unit. They got it here fast! And they care about their customers! With the new carburetor and ignition, my little engine runs amazing! It idles perfect, and loves to rev up every once and a while. This engine doesn’t like to stay at full throttle. Obviously the small carburetor can’t handle constant throttle, and with the long stroke, however it does run very nice. Every carburetor is different. So that was just mine. Anyways this engine really is great. A bit of choke and priming, and the thing just goes! Runs great. I’m a very, satisfied customer!
The simplest of them all, a true collectors item. Fascinating little mechanical wonder, with only a few steps to run it. I love it.
Very nice work, beautiful design and precise machining.
Compression ratio is correct but compression is a bit low even if the engine is starting easily.
Valve stroke is probably a bit short and carburetor full throttle is not enough, making the max rpm quite low and combustion a bit smoky.
Anyway carburator is easy to optimise and mix needles do the job.
Some optimisation which could be done with actual specs (my view):
- Cylinder head screws could have been Torx or Alen, square head is not cool.
- Valve rockers axke is loose, better adjustment would be easy (easy to DIY anyway)
- Compression could be increased with tighter tolerances piston / cylinder
Anyway this is a nice toy to play with ... quite easy to optimise at home.
Ich hätte nie gedacht, dass 4 takt Motoren so klein werden können.
Der Motor kam exzellent verpackt bei mir an.
Er war auch schon voreingestellt, somit lies er sich gleich von anfang an starten.
Verarbeitung der Bauteile war meiner Sicht nach top!
Gerne wieder,
Alles in allem fūr den preis der hammer!!!!
