Yeah it's really similar but the brass parts in the pic are pre-bent plastic pieces on my assembly.

So this would explain why I've had less/no problems since I took everything apart and reassembled - I must have snugged down the bung screw a bit more. I was so worried I wouldn't be able to start my engine at the pattern meet, so I took everything apart and reassembled. and I was able to start with one flip, literally, for each of the 6 flights!

I love AX
