Damazio family's RV-10 project: Engine accessories and heat control cable

I finished attaching the starter and throttle body (cleaning up gasket maker that squeezes out to the inside of the throttle, being careful not to bring any of it into the tiny pressure ports, is not fun):

Back when we attached the governor, we realized too late that the studs' threading didn't go down to the surface of the governor, and had temporarily used 5 washers - I confirmed with Barrett (again, great support!) that this was just a matter of driving the studs further in, which I managed to do with the two-nut trick, and then I secured it with the proper hardware:

Later, the time came to redo the engine preservation - along with the required materials, I decided to get a borescope and check out how the cylinders are doing. Sure enough, there was a bit of rust developing in one of the cylinders (and much smaller patches in the others):

Rust inside the cylinder, already :(

I posted the pictures to the RV-10 group, and Barrett themselves jumped on it :) they decided to have us send the cylinders back for nickel coating, which supposedly makes them more corrosion resistant - so I'll do that just before I'm ready to fly.

For the preservation ("pickling"), the procedure that Barrett gave us was pretty straightforward - spray LPS3 into each cylinder while the piston is at the bottom, twice, so we did that. And because that was too easy, the LPS3 straw had to fall in one of the cylinders 😟 which required some very careful picking to not scratch anything in there in the process:

To prevent the rust from getting worse, I installed dehydrator plugs and a Drybot:

Later, I attached the coil packs on the engine mount:

The aft holes did not align as I had hoped with the adel clamp:

so I'll have to make some kind of support to hold it up firmly at a good angle.

I also ran the aft heat control cable from the pax console insert to the firewall (which required a slightly longer cable than the one Vans provides):
