im having major blow back problems with my invert mini. i have tried following the "invert mini repair guide" on here but still the problem percist. i have also cleaned out the gun, oiled all the o-rings, and resest the board.
any ideas?

First off, Please keep in mind the forums rule about keeping posts correct both grammatically and spelling wise. It really can help people understand you in the long run.

Second off, can you please try and explain what your exactly having go wrong with the gun? I understand blowback but want to know what specifically is happening.

sorry about that bro, english is my second language honestly

uhm everytime i shoot the gun, the second paintball in the chamber jumps back into the hopper, and i think it pops the next paintballs that needs to come down. so i get alot of paintballs that come out of the gun already broken. i hope you can better understand what i mean.

Thats fine, just remember you have a "shift" key (two actually), it makes letter go from i to I or q to Q.

Heh. Sorry, had to do it. Please try to do what you can though. Like I said, it makes things easier for people trying to read your post. Especially important when asking for help from people.

Onto your gun.

What kind of hopper are you using? I can't say I've heard of that happening on a Mini before so. What kind of paint are you using, what kind of barrel, and have you changed around the settings on the board?

So paint is coming out of the gun broken.

Do you need to break down your gun and clean the whole thing to get the paint out or is it just the barrel? If its just the barrel, its likely another problem.

The Mini has eyes to ensure that it doesn't break paint like that. Either your eyes are dirty and need to be cleaned, are broken and reading that there is something there when there isn't, or something else.

I'll try and think up some things but please answer the questions and we can see if theres something the forum can do for you.

okay
I have a eggy 3 hopper brand new, stock barrel and no i havent mess with the board other than doing a defult reset

this is what I noticed when i shoot the gun, some of the compressed air comes out of the feedneck of the gun, forcing the paintballs to jump back in the hopper. This would then cause some to break as they come down into the gun.

i hope someone can help me.
thanks

Please do not tell me that you had any sort of problem comprehending his original post, there's little wrong with it aside from a miss spell or two.
You've never heard of Blow-by, possibly one of THE most prominent problems with the invert mini? You must not have been around for very long; Sorry, I had to do it.
Take a look at this thread and identify what type of poppet you have. If it is not the V1:

Remove the poppet and clean all of the lube off of it, and re-lube the o-ring, only. Make sure that there is none on the face or seal of the poppet.

Also, how long have you had this gun? Have you changed out the bolt guide o-rings recently? Do you have the stock bolt or an aftermarket?


Also, in your original post you said that you oiled the o-rings? Did you use oil or a dow based lubricant?

I would follow the vids in this thread and tear it down and inspect everything. Especially the eyes. I have not chopped a ball in any of my minis.

Good luck and welcome to the forum!

I bought the gun used a few months ago from a close friend. the gun worked fine till few weeks ago, I cleaned it and followed all the guides on here.
the gun has the stock bolt, and v2 poppet, also when i cleaned the gun i used the oil that came in the "invert mini players kit" that i bought online. i hope this help.
im going to put a video on youtube so that you'll can see how it shoots.
thanks by the way
