I see we're back into the dillema of underburning silents, and many fine theories have been proposed as to their cause and cure.
However, I think it's time again to point out the most important consideration of all - SAFETY.
If you search the old posts, you'll find the story of the underburning multi-fuel Optimus 111 that sent me to Hospital with large blistered 2nd degree burns that covered most of the back of my hand.
At that time I was operating the stove with gasoline. I barely noticed the burner had started to underburn until I noticed the cap had started to glow an intense red - it was too late. When I went to turn off the burner it was so hot that the entire shaft had become wobbly from the intense heat. The packing blew out and then the stove became a flamethrower aimed at the top of my hand. Luckily it was winter and I was able to kick the buring stove into a nearby snow bank - my throbbing hand following into the pain relieving snow.
So folks, if you have the slightest reason to suspect your stove may be underburning - turn it off immediately - Don't hesitate - allow it to cool down before relighting.
I might add I still enjoy using my silent burners, but I have to say I feel more comfortable with the operation of my noisy, but less tempermental roarers.

Thanks for the headsup.
Sorry to hear about your mishap. I will keep in my mind that lesson painfully learned at your expense. I am sure others would, too.
