you can try bolt buster on the threads ,let it soak a while that should work. they are hard to get off sometimes.

I here your the man to ask. I have a johnson which was handed down to me ,but we are having problems with it it seems to have a damaged mainspring tube, I straightend the end and was woundering what the overall length is . and I need a mainspring,mine is 11 1/2" the dampner is also damaged the spring does'nt slide on it. it catches and does'nt allow the bolt to lock.do you have a complete unit or know where to get one ?or do you have amainspring,and dampner? thanks
