Robert,
lt hasnt got many miles on it yet, about 300, but it shows no problems yet. There is allso a cyclone.
I took a picture of my charcoal powered Seat filter. The last one since it is now in the hands of a nother owner…
This l wuld recomend to everyone useing charcoal gasifiers. A sack filter made out of a towel. As you can see, when the dust cake gets thick enough, it falls off by it self. Allso no problems with moist gas, the water helps the self cleaning cycle. Just clean it with a vacuum cleaner once every 500 miles or so…
