You may have noticed that after shooting the gun if becomes very hard to unscrew the cleanout plug to prepare for the next shot. Indeed, you may even need a wrench or pair of pliers to do it. This little problem can be fixed by making a handle. Go to the hardware store and pick up a short (about 8 inches) length of thin threaded rod. Also, get 4 bolts that will fit the rod, 4 lock washers and 4 regular washers. All you have to do is drill two holes the same size of the rod in one of the cleanout plugs. Put one hole on each side. Now bend the rod into a half-circle and install a bolt, lock washer and washer on each end. Thread the bolt up about half an inch. Now insert each end of the rod through each hole in the cleanout plug. All you have to do now is bolt the rod on from underneath using the remaining bolts, lock washers and washers. You now have a handle to grip when removing and installing the cleanout plug. If you wish, you can use caulking to seal around the bolt holes.
Carrying around the ramrod you use to push the spud down the barrel could get annoying. This simple add on solves that problem. Get two plastic film cannisters, cut the bottom off one and wrap them with a few coats of hockey tape. Now use the hockey tape to secure one to the bottom of the barrel and the one with no bottom to the top of the barrel. When you are not using the ramrod, just slip it in the holders
Sometimes when you ram your spud down the barrel it falls out the other end because you pushed too far. All you have to do to correct that is to install a bolt right at the bottom of the barrel. It will keep the spud from falling all the way through, and provide a resting place for some smaller objects that you enjoy seeing fly through the air.
Using a dremel, sharpen the inside of the barrel about 1/16 of an inch. This cuts the potato a little bit larger than the barrel and provides a much better seal. This little improvement, if done right, will add on at least 100 yards to your gun's range.
Get a cheap laser pointer and secure it to the side of your barrel somewhere in reach of your non-firing hand. In the evening or at night when the laser is most visible it will provide an accurate sight for up to 3/4 of you spudgun's range.
WONT FIRE If you put fuel in and try to fire it and it dosent or has a very weak fire then:
try a different fuel, use a hotter ignition such as a taser which can be modified to a spudgun, experimant with different amounts of fuell, if using pure gas such as propane open the cap and gently blow into it, this will put oxygen into it, propane is very pickey if it dosent have enough air.
