Thanks for the replies, guys! With your info. I now have another question. I seem to remember reading that you should never use any smoke fluid other than fluid made for Seuthe smoke units. Something along the lines of the thicker fluid can clog the Seuthe unit. I have a bottle of LGB fluid which would be acceptable for Seuthe units.
Have you guys heard of such a thing? Maybe this is what is wrong. My diner seems to work fine though with my JT's Mega Steam.
