PMR not firing/leaking

[JamieMc]

At a game yesterday I went to air up my pmr 07 to have air blasting out of the front of the PMR and the asa and the bolt not firing. I messed with the velocity screw incase it was set to high and managed to stop the air rushing out the front and asa. I adjusted the velocity screw and tried to fire. My results went from air escaping out the back of the PMR to a tiny amount of air leaking from somewhere but the bolt gave a rubbish push forward that wasn't right. That night I was trying to fix it and aired up the pmr and started to try firing while adjusting the velocity. Air started rushing out the pmr, then the bolt started doing the not quite right movement then suddenly the pmr fired properly and air started blasting out of the pmr. On inspection of the bolt o-ring 007 BN70 on the back of the bolt had come off and o-ring 014 BN70 on the very tip of the bolt had snapped.

Now today I have looked at the bolt and replaced any o-rings that looked problematic. I have also unscrewed the reg from the asa and rescrewed again incase it wasn't on properly. I read the "PMR troubleshooting guide" over on pbnation and as I don't have a chrono, set the velocity to 3 half turns from the lowest velocity. What I got was air leaking from either the front of the pmr or the asa and I may have got a leak from the connection from the airport to the macroline...

I don't think this will affect the air leaks but my eye wires snapped and I have been using the pmr with the eyes switched off

I am now completely out of ideas on how to fix this so am looking for some help

Thanks

have you changed the settings on the borad?

 

[JamieMc]

Nope settings are the same as they were when the pmr worked

Thanks

go back through the manual and check that all the settings for dwell and abs are correct..
then replace the battery, after that it might be worth taking an allen key to the reg seat as there is an o-ring on that which may have blown causing a leak from the front.

Will do

Also I was told that it could be the seer had dropped down. Does the pmr have a seer? And could this be whats causing it as my friend said that it usually happens when you adjust your trigger or put a new one in (which I did on christmas day) and that it makes the bolt go into the forward position and release the air which is what happens to the bolt, it goes into the forward position

Thanks
