Just had a good look.

Trevor, In your last video, your latch out lever is constantly latched out and the push rod and/or push rod collar is badly adjusted.

In other words, your governor won't move because it has no where to go.

I believe it only runs because the pushrod set-up is out of sorts.

Thanks for the replies everyone.
Well it looks like the problem was the bolt on the lever that you take off
to remove the cylinder head, for some reason it was tight, once slackened
off the govenor works fine.
Think we'll put that one down to operator error, me !!!.
Trevor.

Hi Trevor, my best advice of the cam follower lever is to tighten it to where it won't move, then back off just a half a smidge like a couple degrees... just enough to let it move freely but not enough to flop around. Then put a drop of synthetic oil on it's pivot point if you haven't already.

Sometimes it’s the simple things. If the valves aren’t  happy, a dribble of marvel mystery oil or automatic transmission fluid straight onto the valve stem (needle spout bottle works nice), and leave it overnight.  It should soften any carbon on the valve and seat, slick up the stem, and leave the valve guides slippery and happy happy.  It might blow a bit smoky for a minute, but you should have compression enough to rope start it. I’m mindful of a photo of an early Indianapolis racer with exposed valve train, and the driver is half out of the car oiling a sticky valve on the fly.
