Honda-SOHC

Using the 8-L would make them even more prone to fouling at tickover and low load,

Must be for high load ,like racing

As interesting alternative Ted

https://www.ebay.co.uk/itm/390062925510 these are flank drive and very low profile ratchet head for access.

Another point for interest (I've already had an alternative manufacturer set like this) is that they make extremely good plug spanner setup for these 4 cylinder Honda engines, with the "pass through " arrangement being able to use the extension and a socket to drop over the plug .... being hollow, both item ... to make very useful reach and access for those two central plugs.

You'd need to check that plug facility yourself though as mine is a different make (now not available) Bahco also owned by SO too.

I have a cheaper Bahco set it was about £20 back in 2021 not sure why this one is so much more expensive.
Not sure what they/yoou  mean by "pass through" ?

Why not? If you can design for whole numbers you can design for half way

They are the same I have. Tip: use a little vaseline, silicone oil or similar inside the upper sealing rubber before you screw the HT wire on. That rubber seal is a bit tight and could therefore resist slightly and give you the feeling you are already there, when in fact you're not. Then you would have a bad connection.

London's Mayor is up for election next week.

Sadiq the Idiot will only be in power if people vote him there. Or worse...don;t bother to vote, thus once more allowing a vocal minority who DO vote to dictate who is in power.
