This week's entertainment: Discovering that, apparently, the plug I
need for the inlet air temp sensor I picked up just doesn't exist any
more unless I want to spend a small fortune importing a repair pigtail
from the US. 
Oh well, that sensor can lurk in the back of my shelf for the rest of time; I'll pick another, more common one to use instead.
Anyway! Remember this bit?
Well, that was only half the synchronisationary goodness! Well, it didn't have to be; I could certainly have done without cam sensing and it would have produced perfectly satisfactory results, but the option was there so I have taken it.
Some time with shears and files has gotten me this, fitted as shown:
Which, along with a dizzy-cap butchered just so...
Lets me do this:
And by making this worse... (It's temporary, for testing only, honest! I promise I have actual connectors for here when I do this for real.)
We get:
Belting! So I plopped the inlet manifold & carb on there just
so it could look pretty for a bit.
And this evening's joy? Well...
...the starter did not like that very much. I performed some bodge surgery that improved it somewhat, but I suspect the real fix will be a gear reduction starter. Going to do some measuring and counting of teeth, then let my bank account recover a little before I get on the blower to Powerlite... (I suspect it'll be somewhere in the region of £300. It'd be cheaper to have the original starter overhauled, I'm sure, but going to a gear reduction one seems like a better solution all round... Well, other than the wallet pain.)
