Howdy, I have an extra muffler for my husqvarna 41 with 40 cc's and I want to play around with it,(mod it) I have the muff off and before I drill any holes I am wondering how big can i go and still have the back pressure? next question, how do I remove the high and low limiter caps so I can adjust the carb when i am done? thanx, Dan
