The HK is a difficult carb to rebuild, the plastic module plate has a tendency to cause a lot of problems in these carbs and usually leak/flood after a rebuild. The needle valve seat wears and won`t take a new needle valve well, there is a seal ring on the plate that tears, distorts when the carb is taken apart plus the module often warps after disassembly.
