What AFR and timing are people running for idle, taxi, takeoff, climb, cruise, descent? 

idle = 11afr, 20 timing
I seem to have to be around 11afr for it to stay alive. Still trying to get it to idle around 600rpm, maybe bump it up to 700rpm to be smoother without dieing and shaking apart. 

taxi / takeoff / climb = 13.2afr, 28 timing

cruise - not sure aft, 28 timing

decent - not sure aft, 32 timing
Not sure what the plane likes. I tried 14afr, but the MAP really get's low and engine shakes. Guessing it should be more rich?

I attached the timing table and split rotary table (second email). Not sure how to tune timing, I just want safe values for now.
