New springs, new seals, new rifle, in about that order.
Real question here. Did it ever shoot faster than it does now, or did you just find out that it is running slow?
How handy are you with tools and such?
The first seal to look at is the one where you stick the pellet in at the breech. To test if it is leaking, place a square of toilet paper over the area and fire a pellet. If the paper moves, there is an air leak.
The Piston seal is the next main culprit. If it is in rough shape, you get poor performance. If it does not fit correctly, same. To get at it, you have to take the piston out, which means you have to get the spring out. There is a strong preference for keeping ones teeth intact, so read up on spring compressors, and how they aid that.
If the spring is tired, same deal, need a new spring. Refer back to the comment about teeth and spring compressors.
Best bet overall, is to troubleshoot first looking for leaks. Then make sure the airgun is properly lubed, using a silicone oil for spring piston airguns. This stuff does not ignite from the pressure of the air being compressed, called dieseling, which is really bad for the seals and the gun in general.
If the breech seal is OK, and a few drops of oil have not restored the performance at least somewhat, you are looking at a teardown and replacement of the spring (probably) the piston seal (really likely, unless it is leather, but that is yet another thing to read up on) and generally going over it to ensure that the piston and seal are working as well as they can.
If you open it up and find that the piston is grinding against the cylinder, it's pretty much f**ked. Buy a new rifle.
If you are not willing to fiddle about yourself, and have a strong desire to spend money, expect to pay about what a replacement air gun is worth, to have someone else do the work. IMO, it's really only worth it to pay to have someone do a job like that, if there is a really good reason, or there is some intrinsic value in the airgun (not the case here, I think).
Check on the Canadian airgun forum. There is a bunch of guys there that are happily modding, hacking, and generally tuning up pretty much anything that has a chance to push a pellet out of the barrel, and someone there will be able to help you through the process, or point you at a parts source (ie: the actual maker of the airgun, which wasn't likely to be Winchester).
Good luck.
