Mine must have been assembled on a Monday morning. I had like .040 on one end and .043 on the other. I was getting 70% efficiency with that.
I followed the instructions that came with my BC an didn't bother to break out the gauges to double check the gap. One of the non-concentric bushings that adjust the gap must be in 180° out of alignment with the knob, because the gap gets wider when the instructions say it should be getting tighter.
Bottom line: get out your feeler gauges and check the gap at both ends.
Mine's now set at .038" on both ends, and I am planning on using it this Saturday. We'll see if my eff. goes up, but I'm really hoping it does better than the 59% I got when I misaligned it using just the instructions and I was too lazy to actually measure the gap. Lesson learned here.
