S410 classic head scratcher
Posted: Mon Mar 11, 2019 8:28 pm
I am having a few problems with my second hand s410 classic 2007. The power is about 10ft/lbs with aa diab fields and i would like it a little more. I have fully serviced the rifle and installed a new exhaust vale and new hammer spring. When I stripped the rifle I found the old spring had and extra little spring on it to boot power but it was still under 9.7ft/lbs then. The exhaust port adjuster screw is full out with no obstruction. The exhaust valve spring can not be wound out any more without air leaking out the barrel.
Any help would be appreciated as I am stumped.
Thanks
