This thing will blow smoke rings for days, so use it outside or with the garage door open.
The engine runs quite well, the mixer/carb is set to run rich for low speed and lean for high speed. Lean condition for too long will cause the engine to run hot, so run it rich and slow.
Fuel mixed 25/1 per directions, using Marvel Mystery oil as it does not gum up.
With a little attention to detail, it can be dressed up to look quite remarkable.
Brass fuel pipe is 4mm, 1/4" wire loom to hide the wire, replaced the brass/copper exhaust fittings for a clean straight pipe, made the wooden box to hide the electronics and added the cylinder oiler. This should come with it imo, but it was fun to search for one and this looks pretty good. Info on the oiler can be found in the video description. 10/32 thread for the oiler.
Would recommend.
Ein sehr gelungener Motor mit einem schönen Klang. Er ist problemlos und bequem über das Schwungrad zu starten.
Als Treibstoff verwende ich Superbenzin mit 4% Zweitakt-Motoröl.
run out of the box.
with 95 gasoline 4%oil or zippo benzine, or diesel. (WD40 too :)

This was not a problem as I planned to make a 6mm aluminium plate base for it
No instructions included at all.
Made the base and protective carry guard and put it all together .
It worked after a bit of adjustment on the mixture screw
Runs perfectly and makes smoke rings from the exhaust
I used 2 stroke mix as fuel
The coolant water is circulated by the piston pump and cools the system efficiently
The large flywheel certainly helps keep the engine rotating while making minute adjusments to the mixture screw
Overall I am very impressed
Einen Vorschlag habe ich aber an den Hersteller eine Riemenscheibe zum antreiben von Geräten würde wünschenswert sein
Ich hoffe die Riemenscheibe wird noch angeboten zum nachrüsten
