masterbuck, i also have a muzzy, but only for a few months. can't help you with fixing it , but i have my cock vane turned up so it can't hit. it should shoot stright as it would shooting with the vane down and it shouln't put a wave in the vane. although i'm far from being an expert. i'm just offering what little i know ,and what woorks for me.it might get you by until your part comes in.
