I have a 201 and a 99 with much the same belt driven motor. I think the specs are the same as the Featherweight's, but the standard motor is a bit larger. Either of the motors never get more than slightly warm, never close to hot like the light bulb can become. I've sewn on machines that later turned out to have bone dry grease wicks and motor axle, they never generated much heat even with decades of neglected service. However they ran smoother when cleaned and greased. I'm sure owner of Featherweights will post more specific experiences on their machines. Hot weather is a factor when running a machine for long, but I sew for hours some times, often with a short brake when the bobbin needs to be wound.
