Invert mini blow back

[Manic_Monkey]

Hi, I don't know if anyone can actually help me resolve this issue I have with my mini but here goes.
I am having some phenominal blow back issues when I say phenominal I mean the ball comes out of the feedneck at a higher velocity than the barrel.

I bought a team spares kit for it, so far I have changed every o-ring at least twice if not more, tried both bolts that come with the spares kit, I've had the dwell set as low as 1 flash and maxed out, I can't tell what the input pressure is since the guage has stopped working, but I've had that turned in as far as I dare, and had it turned out almost all the way.

None of what I have tried has worked even when I had the input pressure set very low and had the dwell as low as the board would allow I still had a rediculous amount of blowback.

I'd had the mini for at least a year before this problem started, at first I thought it might be the cold weather since it began last winter, so have waited for the weather to warm up but it still won't go away.

Any help would be greatly appreciated thanks in advance

Russ, the mini is designed to work at 200psi or a tick below, no more. If you cant read the gauge you need to change that first of all. The input needs to be fairly accurate.

If you arent confident with this, you could always send it to LiPS for a service and fix, or if its under warranty you can contact the store you bought it from.

yeah i know about it needing 200psi or less i used to run it at 180-200ish before all this blowback started, (which was before the guage stopped functioning) but I've had the reg backed out until the mini won't cycle anymore, then wound it in slowly until it just started to cycle and would fire a paintball (I don't know what velocity it would have been doing since i don't own a chrono) and it still sent a ball at least 5 feet into the air from the feedneck.

regardless of all that, you need to get it fixed.

where did you get it from?

 

[Manic_Monkey]

I got it from punishers pb back in 07 so returning it to the shop isn't really an option

Send it to Lips or speak with Kee mate they should be able to sort but. Doesnt sound right though

 

[Bolter]

Exactly, send it in to someone. LiPS will take care of you.

maybe, the air that is supposed to vent from where the trigger is, isinstead being blown out the feedneck.

i dont know about five foot but a ball would still probably fall out. (i might be completely wrong but its an idea)

 

[Mclovin101]

im sure if the mini is to vent any air it wouldnt push a ball out that high. Never had an air ventin out of mine so.

Ring Kee like i said mate they will def be able to sort it
