It's a 79 SF with B38's. Stock exhaust and intake. Starts right up, idles nice when warm, runs good through the gears with normal acceleration but when I crack the throttle and the rpm's rise it begins to cut out (like it's starving for fuel) on at least one of the cylinders. Can twist the throttle wide open at lower R's and no problem. I've totally disassembled, cleaned and installed Mike's kits. Seems like carburetion to me but was hoping someone here can point me the right direction. Thanks.
