Well, I’ve got over 4 hours runtime on my WD now, great little engine.
Had a few minor problems with the pilot truck binding up on traversing S curves, but fixed that by installing larger slide washers.
The safety valve is a typical Accucraft constant feathering type, and a new Wee Bee pop valve will fix that.
I’ve heard lately that the earliest run of WD Baldwins had problems with journal boxes installed upside down and side rods withe elongated holes just to
get the engine to roll. That created a poorly running drivetrain with severe wheel hop.
My engine is Serial #047, and it runs well, so apparently the problem engines were built earlier yet.
Just passing on info for future buyers… Kind of like the C-19 fiasco…
