Thanks guys for the prompt response. Yes, the engine smokes a lot at idle and at WOT, at least on the ground. I don´t dare go full throttle while flying. This engine has too much power for this airframe.
I presume I have room for improvement by working with the needles, so I´ll do that next time on the field.
About the 15% nitro content, is that a must? cause it is so expensive and Bax said you could get by with 0%.

These engines were designed for 0% nitro, but 5% is okay.
Running higher nitro in these engines is a waste of money and is detrimental to their performance and life span. But what do I know? I'm just an old fart with fifty years of experience at this sort of thing. <G>
