I believe it was approx 10 degrees more than stoich burn with very little advance - this was at no load.

I'll have more timing data tomorrow as I'll have to see how much the fuel controller threw the timing out. Here's the thread where I'm putting the data I've collected, which gets updated frequently. There's always something unusual that pops up about this engine. Today I confirmed this engine operates in closed loop under ALL operating conditions.
