Jan, I have had reports that said the engine did run well with a 10cc glow carb (8mm). At least as well as an opposed twin can run. Do not expect them to run as well as a single cylinder, especially in midrange. I have no experience with the engine myself, but did test the walbro carb on a 23cc single cylinder glow engine.

@ RCdude,
Indeed, you should not ask. Whatever it is worth to you. The engine is not produced any more.
