Primus Omnifuel with a silent cap from AliExpress/g43s. The flame isn't as clean as with BD cap but it does the job.
Not a desirable flame, but a notable flame shot nonetheless. The preheater on my Heinze Geniol was running too rich and during one test while troubleshooting, I decided to let it run an extra 3 seconds so I could capture the inferno.
@Tony Press I hope you’re enjoying Hiroshima! Wrapped it’s “throat” in double layer of carbon felt - secured with brass gauze. Needed for double-priming… Carved-up a series of 2 1/4inch brass welch plugs (this is No. 3), trying to find optimal height/diameter for best combustion…
Came across my old handmade BernieDawg silent cap so gave it a go on a freshly fettled Primus 96 this morning.
