Wayne,
I did the same thing with this R60F (new out of the box)side ex on my old standby Compensator. The thing started on the first flip and ran very smooth. The engine is running in the picture but the flash stopped it.
After I ran a tank through I started doing a little adj on the needle, and it came up on the pipe and started singing that song. I ran a couple of tanks through it so I will be ready to get some flying on it @ Hodges !!

Dave.
