How do you get the most out of the ULT?

[Andrew - NYC]

Cleaned up the MAG after a fun time out at Ejam outdoors, and when to setting up the ULT...
I followed the basic step by step set up for the ULT. I was light on the trigger, and I got rapid fire; however, it was a bit too rapid.
I removed a shim, and the gun won't fire at all, or only once. I turn the air off, and then back on. One more shot (or one series of rapid fire), then nothing. No leaks.
Basically, the sear resets, and I get one shot, then nothing?
What gives?

I don't have time to mess with it right now, and really, I needs some ideas?

MAG tweakers please chime in!

Here's a little thread I started up when the ULT first came out. I know you don't have a classic valve, but Bad_Dog has a few good diagram/pictures in this thread, along with a lot of troubleshooting info. Hope it helps!
