what plug is reccomend for this engine?

I suspect you will get a LOT of opinions in response to your question.

In my experience, the european engines run better on low nitro (5% or less) and a hot plug. My rossi runs great on Morgan Omega 5% fuel with an Enya #3 plug. Hope this helps--Good Luck!

I have the new Chinese version of this engine still new in the box. The manual says "A general-purpose R/C Long glow plug will work great in this engine". The factory-supplied plug's length is longer than a OS #8, but shorter than a OS "F" plug. Don't know about the Italian versions.

I use McCoy #59 and 15% Cool Power on the old and new version.
