Today I had a day off as we adopted another rescue dog on Monday, I spent a couple of interrupted hours tinkering with the governor and getting it running again .
I backed the paired nuts off as far as I could and fired it up, it still sounded far too fast but an actual check on is speed revealed it's actually running at 800rpm. I'm more than happy with that. When running unloaded at it's speed the pump push rod can hardly be seen moving at all so the governor cam must be at minimum fuel.
It's a bit smoky and it knocks terribly on the main injector as it runs up to speed but sounds good under load when there. The smoke could be due to the head gasket which is leaking just about everywhere! I'm going to order some proper gasket material from eBay and make one myself. I may have to put a pair of mains in it too as they rumble quite badly. I've heard others doing this on YouTube so I'm not sure if it's a trait or not but I don't like It! There is no lift or float in them at all though.
Slowly, it's getting there.

Nick, would you mind consulting your Uniporn manual again for me please ? I need to determine what type of piston ring should be fitted below the gudgeon pin. Mine had a ridge dodger fitted that can't be right, I wonder if it should have a slotted oil control ring there instead.

Described as an oil scraper ring but doesn't look slotted in the illustration so I guess it could just be stepped - any drain holes in the ring groove?

I'll scan the whole manual at work tomorrow and email it to you.

Thanks a bunch Nick, most appreciated. I can't remember if it has holes around the piston but it won't be much work to pull it out again as I have the head off.

Done (to ford.com addy) - if anyone else wants a copy while it's sitting here, drop me a PM.

I just pulled the piston and there are no holes through the skirt but there is a slot running from the ring groove to channel the oil back to the crankcase. I'm still undecided what to fit TBH.

Hi, I have replaced the oil control ring and the head gasket and the engine now runs much better. Using the starting injector it actually went first time without any heat or starting wicks, it was smoky though! Once up to speed the smoke drops right off to a light haze and I am hopeful that a decent run with a load on will reduce this as everything beds back in.

Here is a video of it running today.

I am very happy with how it runs but less so with the noise the main bearings are making so these may be pulled out in due course.

I'm wondering how much of the noise is down to the steel bearers and less than ideal trolley ?

They definitely aren't helping at all but the mains sound rough even when the crank is rotated slowly. I wonder if its past use had anything to do with it as there was a drive coupling fitted to the governor side when I got it. That side has a smaller roller bearing fitted as opposed to the large ball race fitted to the other side. Until I get them out I can't really decide which one is making all the noise..... I may as well just replace both.
