I get ok performance with one tam nozzle and diesel fuel. just pinch one side a little bit on the nozzle, so it squirts a stream about 3-4 feet, slightly flat looking at about 45 degrees into the cone. it only takes one nozzle to get proper atomization. I tried two and one actually works better, and I can even smoke at idle power. If I used super dri, I am sure it would be dense.

I just use diesel cause Im cheap. I was thinking of adding a quart of transmission oil to 5 gal to see if I could get more smoke, but havent tried it yet.
