3 flights with the 200 in the Valiant this morning. The wind was gusting up to 33kmh, so it wasn't very nice flying, but the engine ran very well with no problems. It's still running rich, but is making plenty of power. it will be a great engine once tuning is complete.
Break in needle is now fully closed and the idle is rock steady.
I'll install it in the Xareltoo now and if the wind calms down, I'll take it for a fly later today.
