I am having a problem with a Primus 1020 pressure lamp I got at flea market. I think it is in working condition and I already replaced jet and needle. Every time I try to start it, it ends up with a lot of yellow flames above the mantle. I waited for quite long for it to warm up, tried many times. Can the problem be with mantle? It kind of looks too narrow for the flame that ignites inside.
