I have been fortunate to buy this well-used, but cared for Radius No. 119 (300cp). The glass is original and it appears complete. I have dismantled and cleaned it out of old insects nests. The pressure release valve was opened and cleaned and appears in working order. I have fashioned a new leather plunger washer for the pump that works. The pressure release valve was found to be leaking air between it and the tank, so I installed a fiber washer that has cured the problem. I am still using a double-tie mantle as I have been able to find a single-tie mantle. May this be the reason for the lamp failing to start up? It burns softly with smoke. Could the reason be that the lamp is getting too much fuel to the mantle? The jet hole is open. I suspect that the red adjustment knob or the needle inside the generator may not be set up correctly. What is the correct sequence to starting up the Radius?
