i recently purchased a bt delta elite, when i first used the marker it was running at 300 to 340 (cronied), now i can't get it past 210, i have cleaned it replaced seals, what else can i do to speed it up?
People think I'm into sports because I'm a man. But I'm not into sports. I like Gatorade, but that's about as far as it goes. By the way, you don't have to be sweaty and play basketball to enjoy Gatorade. You can just be a thirsty dude. Gatorade forgets about this demographic!
I had a similar problem, but out of the box the DE would not chrono above 240fps. I replaced the spring with a stronger one and had no problems getting a proper fps at the chrono. BT sells a spring kit.
I have seen this in at least 3 DE.
