I bought a used Stampede on eBay which outwardly appears to be in excellent condition. But it barely fires a dart 20 feet. Does anyone have any insight on what common problems might be afflicting this Stampede ?

Admittedly I'm a novice, but I'm not averse to cracking it open. I would love to have an idea of what to be on the lookout for while I have it open. Any input would be appreciated.
