I built the Otto- Sempto engine as a gasoline engine, it runs with the Cison CDI and two magnets in the flywheel.
The parts are as always from Toyan clean CNC milled and fit perfectly.
However, Toyan should rethink its concept, I have already built some Toyan engines and it is always little things that spoil the fun of the model.
Poor sealing, carburetor has no clean idle adjustment, even the new diaphragm carburetor can not be perfectly regulated.
The Otto engine also gets too hot because it has too few cooling fins,
otherwise it runs reasonably well.

The build is very easy. Great parts quality as well.

I just finished my l200ac. Went together easy. Runs great. I did have to modify the rocker arms, there was no clearance and the valves weren't closing. I just polished the contact surfaces on the rockers with a fine file then 1200 grit sandpaper until I had a little clearance so the valves could seat. Overall a great buy,

First off the machining is wonderful on this little engine. Within two crank cycles, the glow plug igniter burned out. I have Tried new glow plugs with no luck .
I have reached out to Stirlingkit for a replacement but haven’t heard back from them.

On another note, the carburetor on this engine doesn’t work that well.
I cannot get a good high end, needle, setting or low needle setting. The timing is correctly.
