Hi all, new guy on the forum here, bit of a primus stove nut but relatively new to Tilleys although I have vivid childhood memories of them being brought up in a part of the highlands where electricity did not reach till 1969. I fell heir to a pork pie type Tilley dating from the 1940s but have little success with it, I completely cleaned it, fitted new washers throughout and fitted a new 606 vapouriser tube, despite being properly pre-heated with the cock valve open the mantle does not glow but simply flames, flames emerging from the top of the lamp, partially closing the valve stops the flaming and the mantle becomes partially incandescent but the light output is poor. I have fitted a different burner unit from another Tilley with the same result so, not the mantle. Anybody got any ideas? Thanks Mollbhan.
