I also replaced the 010 on the power tube with a new urethane 010.

Are the delrin seats O-rings or flat washers? Do they work better? I've got black and brown ATF Delrin I can turn on my lathe.
the power tube oring should be nitrile. urethane have no give to them and will hold the power tube open.

either 70 or 90 will work for the seat.

the delrin does not work better. that was the first generation. it doesn't tend to seat reliably. the rings were machined.
