Here's what I've got to work with at present. Didn't seem to have the full adjustment to get them dialled in properly, so worked with what I could... Until I think the condenser on 1-4 packed up and has burnt the points. Might be salvageable but don't think these are great anyway. Daiichi logo on them if that counts for much

You set up the points by adjusting the points and not the back plate.
If you are going by a manual, that is for new Honda points and is just a starting point.
Turn the plate to middle adjustment and then put a strobe light on and adjust the points 1&4, once it is strobed in, move on to  2&3.

Surely you mean the gap is adjusted by using the points but the timing is set by using the backplates don’t you Graham?

Those are not genuine points BB, genuine points have a sort of chequerboard board finish on the surface plate, aftermarket points like those are well known for being hard to set correctly. Set to smallest allowable gap possible and they tend to just time up right then.

DS sells genuine ones for £35 each plus p&p

I’ve got some genuine points somewhere, £40 a pair and I’ll throw in some nice new stainless steel screws for the points plate for, rather chewed up those ones and the wrong type as well, should all be crosshead screws not flat bladed screws.

Not sure if the pic angle is confusing it but the 2-3 points don’t look right, there should be an insulating washer either side of the plate the wires are on, to keep the wires away from earthing out through the points plate.

Yep that red/yellow terminal looks like it maybe compromising the functionality.

Any leak out there and it'll screw with the firing on those cylinder.

I'd move that brass fitting out first to see if it'll pick those two cylinder up.

I never said the word timing  :o
My Honda crystal ball says, he has adjusted the points gap with a feeler to the manual and is now turning the plate to find the timing. And that is why the plate has run out of adjustment.
If he keeps burning parts the points are staying closed too long  ;)

It just seemed to read that way Graham, put the plate in the middle of its adjustment and then use the point gap to time it up is how I read it

Any mention of a strobe means timing to me, dwell meter would mean gap

Maybe you should pop around and show me how to set up points. Maybe my strobe light is no good. You could advise me on if i need a Hondaman box of tricks or that i need to change to electronic ignition. while you are here you could advise me on how to rebore cylinder's, insert valve guides, change valve seats, re grind valve seats to the correct spec, skim heads, alloy weld cases and do fin repairs and so on.

Play nicely you two it does neither of you any credit to squabble so openly on this site.

I have no doubt you are both very knowledgeable in similar areas half the time it reads as just semantics. You are both better than this I'm sure.

Thanks guys all good info and you've confirmed what I thought about the aftermarket points and yes exactly that, trouble setting the timing even with minimum gap.
I used a continuity tester buzzer initially then put a strobe on em... no expert but took my time and did the best I could and enjoyed decent running for 6 months.

Thanks for the offer buddy, very kind. Could do with a nice set of screws for the plate and points tho, if you have a spare set to part with...?
Roo has kindly offered me a great looking OE points and plate so will install that one as soon as I can and take my time setting things up. I also have a points cover in better nick, the anti-conductive paint that was a bit worn on my old one probably wasn't helping matters either 🫣

I would love someone to be able come and show me how to set the points and timing properly. But if there's a good tutorial (vid or other) somewhere that can be recommended in all ears!

You do fin repairs? I have a goldfish you could look at, if it's not too much trouble. He'd be ever so grateful..
