Can someone please explain to me how/where to change my jet?
I just bought a FMF Powercore IV S/A and want to change the stock 148 jet to a 152 jet. Is there an easy way to do this? I heard that theres 4 phillip screws on the bottom of the carb. that you take off, and then there's a brass nut that you unscrew where you can change out the jet. Is this right? I could only find 3 screws under the carb? Any help would be great! Thanks
