Bluebarrels Posted March 18, 2010 Report Share Posted March 18, 2010 anyone know how to change the main-spring in a cometa 300?? ive done a few spring changes before however,the safety on the cometa is located at the back of the cylinder where you would normally take out/put in the spring, any help would be great ,its only putting 9 1/2 ft lbs out, and i would like to get it nearer 11 1/2 ft lbs.cheers BB Quote Link to comment Share on other sites More sharing options...
John_R Posted March 18, 2010 Report Share Posted March 18, 2010 That's about the right power for a 300 though, I think the one I sold a while ago was just under 10. Quote Link to comment Share on other sites More sharing options...
