Scoobsean,

I’ll take your advised and leave the striker spring alone. Right now I just concentrate on fixing the binding problem, and finding way to drill the gas regulator hole. Look like there still lots of work ahead to get this gun to run. Henry B, thank you for your honest commend. This is my first time that I get a none working gun for lots of money and consider myself lucky since the problem seem fixable. My only complaint is that one ought to be honest to stated the working condition of thing they sale, especially something that liability related. Again, thank you all for your help and hopefully I can get this gun to run soon.
