The next item on the table is a late model Jensen 25G. It's by far the newest Jensen in my collection. I got it on a trade, but wasn't that thrilled with it at first as it leaked a lot of steam and had trouble keeping the generator bulb lit brightly without running down.
So I punched some new Teflon gaskets and worked on the throttle a bit to stop the leaks, but why stop there? At the engine, I installed ball bearings at the crankshaft and real balls for the faux governor. The generator got the same ball bearing treatment and two triple pulleys. Somehow I managed to restrain myself and not paint the firebox (for now).
It runs much better now and it's one of my favorites.

In the video we start running slow but soon go balls out and get the genny lighting the bulb nicely. Now the 25 has no problem holding speed.
