Cocker Issues and Apprasail
Just bought a 2k2 centerfeed, single trigger, Autococker from a
buddy of mine. Last time he used it he was having some problems
and I was hoping for some advice. It was showing VERY
inconsistent velocities over the chrono (275, 160, 250, 180, 290,
etc). I attempted to time it, but did not have paint when I was
doing the work. The next time he used it, it had the same issues.
I plan to run the gun exclusively as a pump (CCM economy kit on
order). I am hoping the removal of pneu's may remedy my problem.
What do you think? Could there be some other cause? My only
other thought is that it could be improper bore matching (stock
barrel, lots of roll outs), but I wouldn't expect too much roll out with
repeated shots over the chrono. I'll be using a barrel kit once I get
Also, the gun is in great shape besides the issues it's having. It is
completely stock. What do you think a reasonable price to pay
would be (considering it's semi-working condition)?

Maybe not much. The symtoms you describe says there is a problem, the paint would have to be total crap for those kinds of fluctuations. I would check the regulator for inconsistant pressure, and then the inspect the lower tube, hammer and valve. Could be serious or just worn springs. If this was working correctly, I wouldn't pay more than $100 for it. The value of cockers has dropped out, unless it's a rare custom, but pump kits seem to help there value.

Not going to get much for a cocker these days unless its got electronics.
I agree it is probably the regulator. Try oiling it. If its not that its the valve. Timing is not going to have a great effect on the velocity inconsistency unless its super bad, which if its firing probably isn't that bad.
As far as changing it to a pump, its super simple. You just remove the front block, and the cocking rod and 4 way rod. Don't toss them, you could get a few $ for the parts. then you put the kit on. I am sure there are tutorials on here some where.

Well, I got the gun for $100 including some nice matching blue Revolution shells. Not
sure if I'll to go the pocket hopper or use it with the Revvy yet. I think that the price was
fair for both parties as long as I can get it working with minimal cost.
Is the stock WGP regulator rebuildable? I don't really remember anything about it from my
limited experience with it. Are there any tutorials online? If not, what did you mean
by "oiling" it? Just some Gold Cup in the ASA?
What would the valve have to do with inconsistency? Other than maybe the springs. I can
always check/clean it anyways.
I am getting the CCM economy kit based on a recommendation from Pumpenstien. They
have a great review of it and full tutorial on how to install it. Seems very easy.
When I get the gun I plan on giving it a full cleaning and lubing, put on the pump kit and see
how it works. If there still problems I'll swap out the reg, and if that doesn't help I'll look
into a new set of springs. Any other suggestions?

I'm going to go with reg - that seems the most likely problem. The valve isn't likely to be causing such extreme fluctuations.
Do you have a different reg to drop on the gun? I think that'll solve the problem.
I wouldn't pay over $100 for the gun. Most pumps with kits already installed are selling for $125 to $150 here and on other forums. So, assuming you're spending cash on the pump kit AND prob need to buy a new reg - you're already over market value for the gun if you pay more than $75 or so.

Well, from my experiences, timing and reg adjustment can do this, and of course a sticky valve or hammer. I had a marker timed a little too short once, and was actually catching the hammer as it was hitting the valve. That screwed with my consistency a bit.
Also, I've seen valves with o-rings on the stems (shocktech especially) where the o-ring had gotten gummy, screwing with consistency. But the regulator is, as everyone said, the probably cause of the problem.
WGP regs are easy to deal with. unscrew the two halves, and the piston is right there, waiting to be taken out, wiped down, and reoiled. A dow33 grease is what I generally use, cuz I like it, but an oil should be fine.

Is the LPR adjustable? If so then turn it all the way off. That way the pneumatics are not part of the equation. Then chrono it manually (think pump). This will give you a pure chrono eliminating the chance that timing is the cause. If you are all over the place then it may be the reg, hammer or cocking rod drag, or valve drag (assuming it is not something simple like paint/barrel match issues).
Let us know...

I think I'll be picking the gun up tonight. Thanks for all the great suggestions.
Does anyone know how much pressure a stock Ion reg can put out? That seems
like my most likely choice for a swap (I never seem to use my mechanical Ion....)
I will start by cleaning the entire gun as well as the reg, and see how that goes.
The reason I wanted this gun is due to the single trigger frame Don't see too
many of those anymore (that aren't in horrible condition).

The ion reg will go up to about 300psi - I think. May be a little on the low side for the cocker depending on springs.
I live on the west side of the twin cities. I play at Splat Tag over the river in WI pretty regularly - Darrin is really friendly to pump play. I also hit North Side Sports a couple of times a month during the nice weather for Wed. after work pump games until it gets too dark to play.
I try to make as many Farmland events as possible - including the 10 ball tourney the last couple of years down at Action Packed Paintball Games down south.

North Side has pump on Wednesday nights? I will definitely have to
make it to some of those this summer. I play for the UMN team and
one of our sponsoring fields is APPG, so I've played there a few
times on the airball fields.
