Umm , no , if he's going from 15% to 20% it will probably need to be richened !

At the end of the day , it gets dark .

Its always best to open the needle a half turn or so and lean from there. There's more to it than just nitro content if you're changing fuels, the oil content and viscosity may change as well and it's always easier to lean a motor a bit than to rebuild it.

my thoughts exactly. Its always better to richen the engine first and then re-tune rather than lean it and risk hurting the engine.

It's a complex, costly, glow powered anti-gravity machine!
