Well, I cracked open a new bottle of CP 20% ProPattern, and so the fuel variable is not an issue at this point. The needles are open and there is good smoke, but could the moisture issue, if it was the issue, be due to higher moisture in the atmosphere. It does seem wetter here in Mendocino County with fog about everyday now that Fall is here. I got some props to play with so I will make some changes and report back.
