when i pull the trigger it just makes a pissst noise like the dwell is to low, but it isnt and the bolt doesnt move at all. i have changed the battery cleaned and re-lubed my bolt and changed the internal 0-ring inside the firing can
cheers callum
Most problems can be down to "O" rings. Just the slightest nick or crack can weep air and cause low performance or none operation.the inner of the bolt sleeve 17/70
and the rear three o-rings on the sleeve all 22/70 (most likely the rear as the centre 2 would cause a manifold leak.
also not likely but the o-ring on the end of the right insert 1x3mm ID
