Tips on Changing MTH Smoke Wicks

Good question, I just redid a smoke unit on a MTH PRR T-1 and I have the same result.  I was wondering if you should not put any wicking right in front of the square hole from the fan unit but just between the resistors.  Hopefully someone will chime in with the proper technique.  There was plenty of wicking in the unit I redid and it really fills the entire area around the resistors.

A very important point. It is imperative NOT to block the air path from the fan chamber. Obstructing the air path could also result in the smoke coming out at an odd angle as Kevin reports. 

The secret to getting really great smoke is to not block the air hole between the 2 chambers of the smoke unit. I use 1 MTH wick and squeeze it between the resistors as far to the one side away from the square hole. I fold the remaining wick down as I lower the board on trying to keep it clear of the air hole. I use a dental pick to help push it where needed.

Paul has the right configuration.  I make sure the wick slides between the resisters and is bunched into the bottom of the chamber.  The air flow must be kept clear and use plenty of smoke fluid.  When adding fluid I always add a half dropper full and wait at least one minute before start up.  If I don't wait I get a lot of smoke for a short period of time.  Give the wick time to soak up the fluid.

How much wicking should you use? How long should the wicks be?

I saw video on you tube on how to replace one.

Nice video. I think I used( smoke unit MTH) on Google for a search.
