    I finaly got it after several months, runs well on 2% mixed gasoline or lighter fluid, setting is 3/8 turn. Powered by 18650 battery with USB charger board, toggle switch and a green LED (+ a 100 ohm resistor). I put a 1/4-32 cap to connect the CDI to the spark plug. DO NOT connect the engine ground wire to the ignition case, connect it to the battery negative terminal.

    I received my all metal hit & miss engine a couple of days ago and just made a temporary mount to run it on today. I was thinking about fuel choices and as these engines use a mixer (no carb/jets) I went with alcohol. I use regular 91% "store bought" isopropyl alcohol and Motul 100% synthetic ester 2 cycle go kart racing oil. It runs much cooler than it would on gasoline. It hand starts very easily and the firing cycle is like my full scale 2-1/2 hp John Deere engine. Thanks BangGood!

    Le service après vente est inexistant . J'ai laisser deux messages pour signaler que l"allumage ne fonctionnait plus au bout de seulement 5 minutes de fonctionnement et je n'ai jamais eut de réponses . Le capteur à effet Hall est tombé en panne ainsi que le capteur de secours qui est fourni. On ne m'a pas donné aucune explication et solution pour le refaire fonctionner.

    Классный двигатель. Есть небольшие косяки, но в целом отличная модель. Плюсы: хорошее качество, мощность, простота сборки. Минусы (недоработки): шейка коленвала плохо обработана, может повредить вкладыши; после сборки есть проблемы с землёй, что может убить блок зажигания и датчик хола. Если это происходит проблематично найти запасной. Также есть проблема проскакивания искры на массу. Фиксится диаэлектрической смазкой.

    First off don’t throw away the packaging before fishing out the pushrod! It took me a while to get “starting” figured out. Turns out I was flooding the engine badly. I positioned the gas tank so the bottom was about 2 inches below the carb. I use camp fuel with WD-40. The designer recommends a 93/7% ratio. Now I prime once and it usually starts in 1 or 2 flips. I hid the batt pack and ignition under the base. For the spark plug connection I used a small ring terminal that I split open.

    Packing was so-so, there was a tiny nick on one flywheel and scratches on the gas tank. i will not be using the gas tank anyway. I have seen video of this engine that included a plinth, but his version does not. You must mount make your own mounting to raise the engine up to allow the flywheels to rotate. You need to make your mount heavy because the full-circle crankshaft webs cause the engine to be very unbalanced. In short, it hops and dances if not clamped down. The compression is excellent, and the parts are nicely machined, The blue anodized finish is out of character with this type of engine, but makes a perfect base for paint. I will be painting my engine. Be sure to ground the ignition box to the engine frame somewhere. A wire is included. There are 2 springs on the flywheel governor, one heavy and one light. I removed the lighter spring to slow down the engine. I run my engine on Naphtha with a little 2-cycle mixed in to provide lubrication to the piston. There are no oil cups on the engine so use motor oil in a precision oiler to oil every moving part. I posted a video showing my engine running on a temporary mount. As you will see, it is easy to hand start the engine. I used 3 AAA cells to power the ignition box. Try 1/4th turn from closed for an initial fuel needle valve setting. If you machine or collect model engines (I do both), you will appreciate what an amazing value this engine represents!

    very cool engine and built well. the only thing I’ve noticed is the bushings on the driveshaft are a little sloppy. it would be nice if they were bearings rather than bushings. other than that I have no complaints

    i love this thing, I run it off of methanol and top end lube with a little scent added to help regulate the temperature, when compared to gasoline methanol works better with it having a fuel mixer. It can run for over an hour straight with a full tank of methanol. I plan to make a mini homemade ice cream maker with it. great engine for someone that loves a good deal

    Nice functional educational toy, great appearance. However I am not sure how durable it is regarding continuos running , as there is no lubrication concept. And machines like this, without lubrication will die soon. I recommend to use Fuel/Oil mixture like on RC engines and not Zippo/Lighter gas. The mechanical power is pretty poor as a result of the low compression ratio. Maybe around 15 Watts estimated. It should be enough to charge a phone.
