Thanks to some technical advise from
@replicas it didn't to long to take apart, couple of screwdrivers and a small adjustable, due to a post turning with the screw.
Unscrewed top r/h side ramp, so could get access to screws.
Yes
@kevlar clear plastic cover just above the gate, which made me think that magneto might have to be removed as that appears to be on clear plastic as well. Anyway removed 2 screws that I could access on clear plastic cover, 1 screw a pita as post unscrewed at same time, and then cover swiveled round so could access gate without removing magneto.
Whether or not it is the correct screw, no idea, all I can say is that it protruded 4 if not 5mm underneath the gate bracket.
Unscrewed it totally and used Kev's idea of spacing it out with washers, luckily had some plastic spacers, and put 5 or maybe even 6 on as a temporary fix. (see pic below)
Screwed back in with spacers on and not protruding underneath but then gate wire was catching on side of spacers, as there seemed to be sideways movement of wire/was a bit too wide/long.
So thought take gate/wire assembly off and just trim the end so that it didn't snag on the side of the spacers. It was only then that I saw that it was not an original wire gate, not even round, a repair/bodge whatever you want to call it made from a piece of flat wire!! (see pic below)
Fully working HUO it is not


Anybody got a spare wire gate??
