Well, I finally got around to taking the 67E apart. I found that the hook of the spring was not even close to being caught by the 'pin' on the hammer. After about an hour of bending, rebending, etc., I think I have the problem solved. I won't know for sure until I get out to fire it few times. I may get a chance later today or tomorrow to try it.
Red, Wrangler, I found the website you referred me to be a lot of help. Thanks to all and I'll let you know as soon as I find out how well it works.
