Having trouble with air leaking down the barrel? This is for you!
Alright, first here is where you can buy the valve pin. The valve pin is what causes your leak. It's at the bottom of the page.
Now here's the step by step instructions with pictures (sorry they are a little dark, but you get the point)
First get your pimp if you don't already have it
Second, Take your lpr and unscrew it and it will look like this:
Ok, now when you take that off the back of the lpr is still attached to the marker so you will have to take a crescent wrench to the front of it. On the front there are two flats, however I can unscrew mine with my hands whatever works for you though.
Now that you have that off you will see a spring inside the gun with a black piece at the end of it which is your valve pin
Once you get the valve pin out (it's not too hard to get out, just shake your gun a little if it doesn't fall out at once) check for wear along the edges or see if any chunks are missing lol. Here is how it all should look kind of:
Now, once you replace the valve pin then you have to do the patented daveczrn bag trick on your lpr so it will be consistent. It's on the first page of the pimp FAQ
