Hi guys Ive been reading your forums for a few weeks now and its been a lot of help!! Im currently building a Blaster for my wife and just received Barnett clutch plates. My question is Ive watched youtube videos of a clutch installation and one video has a smaller steel ring and a smaller friction in the video and in my kit all the steel rings and friction rings are the same size. Do I use a existing small ring that is in the old stack? The ones Ive got are all in separate bags with no instructions. Its been a while since Ive done clutch plates and have never done a Blaster's before. Also I have a jetting question..I just bought a toomey B1 kit that come with a uni filter,air box vents,v force 3 reeds. Ive port matched my intake to sleeve,done transfers,and polished exh. until I can see myself in it. My elevation is 300 ft (crooms Brooksville FL)..will the 310 be enough or too much for everything I listed plus elevation. Thanks for any help...I do appreciate it I:I
