has anyone heard of this? i totally rebuilt my stock cb360 petcock(gas is only coming out of one fuel line and then stops)i checked main jets and pilot jets, look great with no gum up,(used air compressor also) diaphrams are new, intake boots are in great shape, it is still running like shit, like its running out of fuel around 4,000 rpms until 8,000 rpms. runs great 0-4000, i figured it was main jets clogged. points gapped correctly and valves have been checked, any ideas? You guys told me to read up and and bust into mechanic mode, which i did, everything looked brand new. which previous owner did give me receipts for carb rebuild in 2010.
