With 120 on each half of the 240, you should have approximately 208 V to the generated phase. if you have an equilateral triangle with the bas 240 units wide, the height should be 207.8 units. (sin 60 degrees * 240 = 207.8). Or, measuring between all 3 lines should give equal voltages. Yours is not equal, again. Your 1 - 3 voltage is quite a bit too high.
Either increasing the cap values or adjusting them to get better balance ought to help.
