Rick and Marty,
I appreciate your help!
Here is a picture of the Hudson with the dome removed. The magnet is in the picture next to the dome. the metal peg is in the bowl. Looking at the top of engine where the dome goes it isn't clear to me exactly where the peg goes and where the magnet is supposed sit inside the dome. sit on the dome. I am concerned that I might end up letting the peg fall into the smoke fluid reservoir hole if I am not careful. I will cover it with tape.
See attached picture.
Thanks,
Richard
