Thank you for the tips I will try it and see what happens!
The easist fix is to blow down the stack first to clear the stack out. This usually gets it to smoking enough that you can burn the fluid out and start over
You can also twist the corner of a paper towel and stick it down the stack for a few minutes. It will absorb the excess fluid. Do it a few times with a new section of paper towel. It's quicker than letting it sit upside down.
Easier than a paper towel is a Q-Tip, and it'll soak up a surprising amount of fluid. Don't ask me how I know.
