I have a Stihl MS230C in for repair of what should have been a simple job. It hadn't been run for two years. I disassembled the carb, cleaned it in our sonic cleaner, ordered and installed all new gaskets, and reassembled it. Now when I prime it to start, I get no gas flowing into the carb. I pulled the gas line and gas spewed all over me. Apparently, the primer worked in pulling gas up to the carb. It just stops there. I disassembled it again to check if I perhaps assembled it incorrectly. I did assemble it correctly. I checked for flow through the intake and it's clear. When I assembled and installed it again I have the same issue. Any ideas what could be constricting the flow after assembly? Thanks
