The large Bing has a lot of blow by. Also a previous owner really goobered it up with a lot of needless soldering to put it together.

Plan to tin the connecting rod and inside the gland to reduce the slip to reduce the blowby. (Mostly from the gland.) I've had success with other engines doing this with lead free tinning flux. The formula is nearly identical to Babbitt.

However, I need to remove the piston rod end. Typically I've seen that threaded, but it might have been pinned on this engine?

One of the screw holds to hold the cylinder down is badly and largely drilled out. I think I will solder in brass screw stud. (The previous bodge simply soldered the cylinder down via that hole!)

I noticed the valve linkage is slotted to allow for adjustment, I wonder how much difference that makes.

I still have a bunch of solder to remove from the cap. Sadly the cap jacket is badly cut. The jackets are not just ornamental, they provide some insulation. (Steam jacketed cylinders improve power.)

The engine running, notice the gland blowby. I need to remove the crosshead

I have more to clean up on the cap. To remove the excessive sloppy solder.

Unfortunately one of the screw holes is badly drilled out (why on Earth??) So I will solder in a brass screw with the head preserved. [ Guests cannot view attachments ]

Looks I can adjust the last linkage to tune it. Any tips on static tuning?
