Lionel legacy m1a smoke fluid port

Its strange that Lionel didn't post the manual for this one on the website.

The parts directory shows a dual smoke unit under the stack, so that would indicate filling through the stack.

Keep in mind these dual units are thirsty and you may want to give it a "night before" fill , or wait a day to try the smoke unit so the fluid has time to get absorbed into the second reservior.

The fluid only enters one side through the stack, than it gets absorbed into the other side of the unit once it gets under the divider.

Thanks RickO.  Good detective work.  And I think you nailed it regarding time needed to absorb through because on one hand I am getting the spittle out of the stack from adding lots of fluid, and on the other hand a bit of that burnt wick smell from whistle steam smoke.

Note that the whistle smoke side is always on low heat whenever the smoke is enabled, so it's important to always have fluid in there.  The reasoning is when you sound the whistle, you want immediate smoke, so the pre-heat is necessary.

Thank you.  I did notice the faint sent of the burnt wick, even with the smoke "off" via cab 2, which now makes sense due to the lag time with the dual use reservoir, and it was likely dry. 

When you command the smoke off, the whistle smoke resistor "should" not be active, but anytime the smoke is on, the whistle smoke resistor is preheated to be ready when the whistle is sounded.

Ah, got it. Thank you.
