Cheers everyone I think Ill try going a little lower on the jet sizes to see if we can get the pressure back up and maybe see if I can shim them out a bit to add restriction. Can you get a shim kit for these rockers or will I just have to find some that fit? I wont get to be with the car for a couple more weeks til we get back to the track so I'll just have to wait and see how it goes I guess. I really dont wanna toast his top end so I'll just have to keep an eye on things as we go!
