This is an odd one, but I'm having a heck of a time getting this thing to take smoke fluid with the shell on. It seems to just be pooling in the funnel and over flowing. I tool the shell off and cleaned everything up. Takes fluid fine and smokes great without the shell on. Put the shell back on and it smokes fine, but when the fluid is gone and I add more it just pools in the funnel. The smoke unit hole isnt visible from above due to the configuration of the smoke stack. The shell underside has a conical shape cast into it over the smoke unit. I assume this is to disperse the smoke so it come out of all 4 stack openings. Is there a known issue of too tight clearance between this piece of the shell and the fluid funnel? I plan to take a dremel to the conical part of the shell underside since it seems to be the only thing which could cause this issue. Thanks

Take a small LED flashlight and try to get a good look down the smoke stack Rick. Room light doesn't penetrate the small dark cavities.
When you had the shell off could you look up from the inside through the stack and see light and not detect any casting issues ?
If there is a gasket between the shell and smoke unit funnel it should be fully seated properly.
Only fill the smoke unit while the smoke fan isn't blowing up through the stack .
I just use a needle/tube tipped smoke fluid bottle to completely bypass this kind of problem on so many engines. Searching any of the popular online retailers for Needle Tip Squeeze Bottle will result in a huge number of hits.

Thanks to you both for replying. I used the needle oiler. I already use one to get smoke into a smoking hobo building, so I used that. Worked great 👍
