Ha, Dot bottom/Dot top, makes no difference in the grand scheme of things as it swaps from bottom to top every 360 deg rotation of the crank, but the book (for a 170cdi) says bottom so to the bottom it goes.
After 1.5 flights yesterday, I'm sort of back where I started the whole saga. It'll do a schedule but the reg and needle needs to be super lean that it won't load up but it still will if you don't clear it out every now and then. Needle is set about 2 clicks to the lean side of peak rpm, which isn't the safest way to run it.
Time to put the thing away until the new head assembly arrives. I'll post back when it does..
Edit: With the V8 supercars putting on their usual boring show and the MX track a muddy slop it was off to the shed to turn up a dummy cylinder to bolt the head to, so as to test the sealing of the valve seats.
