    Model engine that runs

    This is a very nice looking engine and displays very well it does run nicely HOWEVER it doesn’t appear like it was actually designed to run for long in any practical sense my point being the crankshaft bearings are the engine case itself and no crank seals are present, the engine side covers have no gaskets installed, the valve lifters are brass on a steel cam with no real way to lube itself. If you add oil to the crankcase it very quickly throws it out of the aforementioned places and then no splash lubrication of the camshaft. I used RTV and sealed the left side cover and then made a paper gasket for the right cover so it could be removed when needed I’ve ended up using a light grease and oil mixture to fill the crankcase with it seems to stay in place better and it lubes the camshaft lobes better than just oil. I sanded and polished the machined surface of the flywheel and took a little bit off of the governor spring to slow it down a little bit Jen is a wonderful designer I just wish he had actually built this engine to be used instead of just looking at it

    Neat Little Engine!

    With a little tweaking and carburetor adjustment the little engine idles and revs nice! I did eliminate the flyball governor and installed a throttle return spring, only because I prefer a low idle and ability to rev it a little. Overall quite happy with it!

    Very nice little motor. Struggle to get it to run - overfuel and spit petrol out of exhaust. Not sure what the problem is maybe timing not correct

    Toller Motor mit Verbesserungspotential!

    Der Motor läuft hervorragend. Die Einstellung des Vergasers ist allerdings extrem feinfühlig. Die O-Ringe für den Antrieb der Wasserpumpe und des Lüfters sollte man durch etwas Anderes ersetzen, da sie sehr schnell altern und reißen. Leider fehlt ein E-Starter. Damit wäre der optisch sehr ansprechende Motor beispielsweise perfekt für ein offenes Modellschiff oder einen Oldtimer geeignet.
