Signs of a Bad Regulator?

When I was shooting the gun four days ago, it was shooting really good. The pellet velocity was at 748 fps. I put the gun away and didn't mess with the gun. Two days later I took the gun out to finish my video I was making and out of no where the gun was off. That's when I brought out the chronograph. I watched several videos on YouTube this morning and I'm about to take out the regular. I just need a cleaning rod to get to it

Did you try to adjust the hammerspring? They can work themselves loose. It might be something really simple & opening up that buggah could cause you unnecessary problems. 
 
Michael, you were right. I tighten the hammer spring and the gun is shooting great again. You saved me from a real mess. The screw for the hammer spring is really easy to turn and from taking the gun from backyard to my gun closet, the hammer screw some how loosened. The screw turn almost 3/4 of a turn to get the gun back to where it was shooting. Maybe I can put Teflon tape on the threads on hammer screw to give it some resistance so it doesn't back out again

Good deal. I would recommend a drop of BLUE loctite. It takes about 20 minutes to set and cures in 24 hours. That should give you ample time to apply the loctite and adjust it using your chronograph. BLUE is removable so if you ever want to change it, just break it loose.
