I'm reaching my wit's end, and any and all advice would be welcome. I've got an '81 Special II, it's all stock, with BS34s, and I can't get it to stop with the popping. I pulled the carbs and did as best a disassemble and clean as best as I could. I replaced the mixture screw o rings and both are turned out to three turns. I've checked the float levels and both are at 22mm. I've tried synching with a manometer of my making and all seems right. What am I missing? Is getting these right that difficult!?!?
