mini problem

[philfull]

i have bought a mini recently and upgraded the board, spring, detents and bolt as it came as a package.

the problem is when fireing the gun the bolt only moves forward about 2mm and doesnt return then moves another 2mm per shot untill it jams fully forward.

i have tried altering the dwell settings to no avail and reset the board to factory settings and no joy.

i have replaced the ups with the stock parts (exept board) and still have the same problem

the board is a yakuza and i have set it to their spec and it still wont work.

any advice please

yeah mate lubed it cleaned it lubed it again and so on but no joy

 

[MJ]

It wont be your dwell.....Maybe input pressure....You tried turning up your velocity ?

-MJ

checked that too 200psi input but cant check velocity as the bolt doesnt close and the air vents up the feedneck but scewed it fully in both directions and no joy

 

[MJ]

do you know the velocity its firing at ?

-MJ

 

[philfull]

no mate never had a ball through it yet as it wont fire

Ok i will let bolter sort it, im not too good with minis lol but initially i though it was bolt stick...

Hey i tried

erm, u overtighten the back screw cap? if you have done it represses the action of the bolt, so the looser it is the more freedom it will let the bolt have to move.

might be a newb suggestion but is your spring in infront of the bolt in the right way
