OK - done but something's askew. It turns out removing the shell wasn't necessary. My initial grease job worked just fine.
Leighline Chris suggested that I pull the motor in order to pull the bearings out, clean the gunk out of them and their housings. I pulled the motor and she spun as good as a top. I did not see a way to pull anything out so I left well enough alone, screwed it back in and just added a drop of lube at each spin point.
Anyhow: Now when I run her it require substantially more voltage to obtain previous speeds and I also hear a very fast clicking sound, from the engine, when I blow the whistle.
I never was good at leaving well enough alone. Any ideas?
