Please help. I have a .68 Carbine. I dont remember what
year but it is in mint condition and I only played with it about 6
times over the years. The problem is that when I get the marker
chrono-ed the FPS stays around 300. The velocity adjustment screw
is all the way in and it cannot be adjusted down anymore. This is
bad because the field I have played on has a speed limit of 290
FPS. Any suggestions? This marker has always had this
problem. I never noticed it before because I never had the speed
limit less than 300 until recent. This marker is incredibly
reliable but has this one problem. I also have installed on it a
smart parts extened rifled barrel. Any help is greatly appreciated. |

remove the main drive spring... cut one or two coils (no more, for starters). That should do it. If it's still too high... cut down one at a time, but be mindful that cutting too much off will result in the gun not cycling.
Next chance you get, see if you can get a spare drive spring, just in case. Always good to have spares. A drive spring for an X7, A5 or 98 are all interchangible with the 68carb, so they shouldn't be too hard to find. |

Cutting the spring should definitely do it. I had the same problem on my 68 carbine and I also had to cut the spring to get the velocity down. Mine was worse though, I think it was at like 340 or something absurd. I cut probably about 2 coils off and that dropped it down to a safe level. If you cut too much, go to http://www.tippmannparts.com - www.tippmannparts.com and you can grab a new one without buying a whole kit.

| Thanks for the info. I have not looked at the spring yet. Does the end of the spring have any special features like ground flat ends or anything like that? |

Nope, just standard bent ends. Precision isnt too critical. Good luck,  68 Carbs

Ditto, that thing is a tank and has a certain aura of awesome about it. Only thing that sucked was the plastic feed neck which I just replaced. ------------- oreomann33: Everybody invades Poland Rofl_Mao: And everyone eats turkey Me: But only if they're hungary Mack: Yeah but hungary people go russian through their food and end up with greece on everyth |

Thanks again for all the help. I have also replaced the plastic feed neck. Thats the only complaint I have about this marker. I have my plastic neck supported with 2 wire ties to prevent it from coming off during play. So far so good. Great marker but bad neck design. I played last weekend and so many people were asking me where I got a 68 carbine in such perfect condition. Some were even considering making an offer for it. |

You can get a metal feed neck to fix that instead of tying it down. I doubt you'll find any stores that carry it now but if you look around on ebay or something you may find somebody willing to sell one. That's how I got mine.
