although the page is far from complete, the two principle tune-up guides, mine and (with Craig's permission), Craig's (Co2unes) tuneup information have been published to my website and are now available. His is extremely informative. Between the two, they provide a lot of information that both the "novice" and the "advanced" persons will find easy to read, understand, and relate to, and if you don't find or understand it in one, it's probably available in the other. Take a look at it.

For those DYI'ers that want to simplify take a stab at Co2 tuning, I am also considering putting together a complete "tuneup kit" to make it more convenient. It would include all of the correct o-rings of the right composition and durometer, trigger spring, breech seal, probe seal and replacement Allen set screws for both the barrel and bolt for the QB-78's, for both the .22 and the .77 if the demand and/or interest is there for it. As many of you know, the general hardware store parts though they may fit, don't usually hold up for long and are not made of the correct materials. Let me know your thoughts regarding this.
Thanks all:
