smoky

Here's my problem, I have an older bear blackbear bow @ 58# peak with wheels. I shoot fingers and I have string and cable (not the best but works) silencers. The problem is sometimes i shoot and my bow barely makes a sound, and sometimes I hear a loud but low thwang. I am thinking i might be torquing a little right, but not quite so sure, because I have good arrow flight.
Any suggestions? As always thanks in advance.

check the nock on the arrow that it makes that sound when shooting, It maybe to tight of fit on string. If so just run it up & down the string a few times or use a file. just a thought
