Hi all, Im new to RCU and really appreciate all of the help that Ive already received just from searching the forums with problems Ive had. Now I have a new problem and cant find an answer, so hopefully you guys can help me out!!

I just finished my Lanier 1.20 Edge with 1.60 FX and Im having trouble richening the engine. I know that I can pinch one of the stingers on the BCM Muffler, but does it matter which one and how much???? And just a question for the heck of it, Will I change the performance of the pipe if I was to cut the stingers a tad shorter? Thanks to all who reply!
