Default TOC 53 question

I bought the Honda Sukhoi package with the TOC-53 from WH in the summer of 2007. Life got in the way and I just recently finished the plane and got it in the air a couple weeks ago. I had run the motor on a test stand for about an hour before installing it on the plane then added the hop up kit before the maiden flight. After six flights, I'm turning just over 6900 rpm max (measured with a Fromeco tach, 6954 was the highest reading yet) with the 22x8 "bunny" prop.

The temperatures have been fluctuating quite a bit in north Florida lately and I suspect I had a lean run yesterday as after a couple minutes in the air, the engine wouldn't take more than about 1/4 throttle. I landed long and taxi'd into the tall grass at the end of the runway and tweaked the left gear and tore up the wheel pants so I couldn't richen the high end and try another flight.

I'm curious as to what kind of rpm others have seen with the 22x8 bunny prop and how much run time it took to get the motor broken in. Also, I used a degree wheel last night to determine that the static timing was approximately 22 degrees before TDC. I had read that it should be set at 30 but even after lengthening the slots in the sensor bracket, the closest I could get to 30 was around 27. Has anyone else experienced this?

Thanks to all,
Rick
