Few months ago i bought this engine as unknown. I though it was in a quite good condition and i will renovate it. The problem is that the engine is still a mystery for me… At first it looked similar to pre-war Villiers or old Jawa. Unfortunately after spending long time searching the net for some detailed photos i still can not say what it is. The engine is two stroke, double port, capacity around 175-200ccm. The piston has a deflector. Inscription on the engine casing says: “21333” and “Z2 V175”. There is another one on the decompressor cap: “RAVA” or “RAWA”. Now the most important – little logo extruded on the bottom part of the cylinder that you can see on the photo.
Thank you in advance for any help
