If your gun is burping look here:
BURPING-when a paintball marker cycles without the sear latching the striker/hammer (burping AKA: going full auto, farting, etc...). Burping is
cause by air restrictions, excess friction, blockage, air leakage,
improperly assembled markers, inadequate cocking pressure, inadequate
backpressure, improper lubrication, and worn/broken parts.
Check your power source, make sure you have adequate cocking pressure. If you think you have a power source problem, go fill your tank up and try to
shoot your marker with a full CO2 or HPA tank...
Check all your O-rings. This includes valve o-rings, vertical adapter
o-rings, bolt O-rings, low pressure chamber/valve plug o-ring and the
striker O-ring. (See Pictures 1 & 2) Replace any that are worn or broken,
keep in mind that some O-ring damage is too small to notice with the eye
(although it still may affect the gun as if there was no O-ring there at
all).Check your cup seal. Replace it if its damaged (sometimes cup seal damage is not noticeable to the human eye). (See Picture 1)
Make sure your valve body screw is flush with the receiver. It may cause a
flow restriction if screwed in farther. (See Picture 1)
Make sure you have oiled your gun and make sure to use paintball specific
oil. Other oils may damage the O-ring even dissolve them. Different oils
have different viscosities and temperature tolerances also, its a good idea
to use paintball lube that won't gum up your marker in cold/hot weather. Oil
all O-rings, bolt, striker, and put a few drops in the ASA (then shoot a few
times without a barrel).
Check for any kind of valve damage. Any damage whatsoever can cause
re-cocking and/or leaking problems. The valve is made of a very delicate
metal that scratches easily. If the valve is damaged replace it. To avoid
valve damage, do not remove the valve unless you are replacing it or
upgrading it to another higher flowing turbo valve. (See Picture 1)
Check the valve pin for damage. Make sure the pin is not bent and seats
properly on the cup seal and contacts the striker/hammer pin. (See Picture
1) Check the sear for excess wear. If it is worn, it will not catch the
striker thus cause burping. If damaged, replace it. (See Picture 4 )
Check the striker for excess wear. If it is worn or rounded, it will not
catch the sear thus cause burping. If damaged, replace it. (See Picture 2)
Shoot your gun with paint. Some guns just decide they don't want to re-cock
without paint. The paint gives the gun just a little extra backpressure to
re-cock.
Check for any flow restrictions. Make sure there is nothing blocking the gas lines to your valve. Take out any gunk and the stupid factory filters
which Kingman has thrown into the lines. These will all cause air
restrictions which can cause inadequate re-cocking pressure.
If you are regulating your gun, make sure the regulator is set to allow
adequate pressure for the gun to re-cock. If you think this is the case,
simply turn up your regulator.
Look in the inside bore of the receiver. Where all your internals go. Check
for any deep gashes, scratches or burs that may cause leaking or excess
friction, both which may cause burping. (See Picture 1 & 3)
Check the valve chamber plug, if you have an older standard spyder, make
sure the plug is flush with the receiver (body).
Check your Trigger Frame to be sure it is secured to the receiver. If it is
loose, the sear and striker may not engage causing burping. (See Picture 3 & 4)
If your gun is leaking, look here:
Check your power source. If there is not adequate pressure to seal the
valve, air will escape through the barrel. Make sure you have a full tank.
Check all your O-rings. This includes valve O-rings, vertical adapter
O-rings, bolt O-rings, low pressure chamber/valve plug O-ring and the
striker O-ring. (See Pictures 1 & 2) Replace any that are worn or broken,
keep in mind that some O-ring damage is too small to notice with the eye
(although it still may affect the gun as if there was no O-ring there at
all).
Check your cup seal. Replace it if its damaged (sometimes cup seal damage
is not noticeable to the human eye). (See Picture 1)

If your gun is breaking paint, use this checklist to determine the cause and
possibly fix. You will first determine where the paint breaks are occuring.
For chopping in the breech:
check bolt for burs
check reciever for burs
check powerfeed plug make sure its aligned properly
check nubin for excess wear
make sure your not using crap paint
use a revy
check your velocities
cold weather makes paint brittle-take that into consideration
modifying the bolt so it cups the paintball better will help
going LP will be gentler on the paint
oil your gun
For chopping in the barrel:
check barrel for burs
check paint/barrel match
make sure your not using crap paint
check your velocities
cold weather makes paint brittle-take that into consideration
going will be gentler on the paint
Low velocities? Here is a bunch of fixes to your problem.
Screw your velocity adjuster in further
Put a stiffer main(striker) spring into your gun
Put a lighter valve spring into your gun
Turn the output pressure of your regulator up
Make sure you are using a good paint/barrel match
Use a barrel with less porting
Use higher flowing internals(vertical adapter, valve, bolt)
High velocities? Here are some fixes.
Unscrew the velocity adjuster some
Put a lighter main(striker) spring into your gun
Put a stiffer valve spring into your gun
Turn the output pressure of your regulator down
Use barrel with more porting
