You don't have to replace the carb body. I have a 79SF that has the same carbs as yours and had 3 broken off tips, two that I had to drill out. The holes are larger than normal, but with new mixture screws, it idles smooth at 900 RPM. The points just stick down into the carb throat more than usual. I had to shorten the springs a bit to allow this. The adjustment is much more sensitive now and takes a little longer to tune, but works very well. YMMV.

79F - owned since '89 - FJ fork mod, solo seat mod, Dyna 3Ω's, 14MM M/C (168K miles)
79SF - every day rider, solo seat mod, Brembo 16MM M/C, Accel 3Ω's, Supertrapp (125K miles)
