RE: DLE-30 Carb Wont Draw Fuel
The metering needle could possibly be stuck, even a mal-adjusted fulcrum arm wouldn't stop the fuel from flowing when choked. You did open the needles after rebuilding. right?
When assembling the pump side you did put the diaphragm first (flapper valves) against the carb body then the gasket, and the reverse on the metering side??
