Bello , suona bene e ha giri costanti ottima messa a punto
E' possible sapere un po' di dati quali : elica / miscela / candela usata / lunghezza della risonanza / giri al massimo
Grazie e saluti dall' italia

Hello, thanks for your comment. Some information is given in the description (fuel and prop size). The resonance distance is roughly 29 to 30cm. The glow plug is medium ("3" is stamped at the top but I could not find the manufacturer). The pipe is from Graupner and is made for 10ccm engines but in my opinion works good in this combination. When I bought this engine long time ago it was quite a challenge to find a good setup with the standard muffler in the first runs and I thought maybe the carburator is not so good but with the resonance pipe it runs really smooth and the temperature was lower than with the muffler. This setup could reach 14000rpm, I think. Kind regards...
