Yup, had that mental discussion with myself whilst chewing on-it. I remember ping it three times before I was happy. It’s deffo in right.
I crossed that off a while ago and concentrating on all ‘spinny’ things but hadn’t for some reason, thought of the starter. I was hoping to fire it today n all bugger!

Aaah, cheers Andy, do you know, I don’t know what the forum would do without technical brilliance such as yours.
Saying that, if it was a land rover, I would

Yeah those 2 Roo. It's possible to overtighten them and that puts pressure on the armature as it compresses the space it has to fill.
Does the squeal come from spinning the motor over but it not firing up or when it's fired up and it gets turned off.
If the former does cranking the motor over by the kickstart produce the same noise, if not it's pointing to a starter motor fault, if it does then it's an engine fault somewhere.
My BIL had a similar problem when he built up his or should I say my 500 last time, kept complaining of this squeal just as the engine died, turned out the camchain tensioner wasn't in right.
It was why I kept saying to you to check, check again and finally do another check. I always fit mine in the barrels before I fully lower them, if the barrels are fully down it's really hard to locate it properly, when they are raised an inch or so it goes it pretty easy.
You could also try releasing the camchain tensioner adjusting bolt, if the chain is overtight for whatever reason it would allow it to slacken off a little as the engine spins. With a new chain there is little danger.

Well, bit of coaxing on the throttle and it fired in the first attempt……..which is nice!
However,
The Parp is evident on engine stop and restart. Bugger!
The tappetts aren’t quite there so that’s my first port of call now, then delve back into the clutch as I checked the starter, all good, re oiled up, put back and no dramas. Presumably I’ve not done the valves as well as I could have after todays lift of the lid so sort that and clutch.
Plugs were sooty black, to be expected with the wrong jets, air filter, pipe etc but that’s to fettle in a bit.
So far……..ball bearings in a baccy tin

That was just a zinc plated part that was yellow passivated in its original form ;)
