I have a one year old 2hp Grizzly cyclone (sneaky late gloat) that I think has a leak somewhere in the exhaust. My reason for thinking this is that I can run the cyclone after not being in the shop for a day and smell and taste dust in the air. This is with one unused port open and no tools running.
To find the suspected leak I plan to use a stick of burning incense or something similar to try to find air movement around connections, although I'm not sure how well it will work near the filter.
Any other thoughts or ideas are welcome...
