The points should be closed on approach to F mark and should open exactly on the mark. Move the backplate until it is perfect, then adjust the 3/4 side by moving its own adjusting plate without moving main backing plate.

Cheers,.that makes more sense! I had it backwards.

But I have given it a good many tries and I just can't nail it. Set at 0.3mm and 0.4mm and just can't get the adjustment required. Not sure it's the spark advancer or I'm just fundamentally missing something. Videos show this process to be fairly easy.

Set it at 0.2 and see what happens.

Are they TEC points or Daichi?

TEC are standard points and the best, Daichi are known for not allowing 2/3 to time up correctly unless you reduce the gap.

I have a TECuni5 and checked again that dot/mark on the cam is facing the TEC stamp on the plate.

I'll give it a go with 0.2mm shim as well.

If you cant get both side spot on F with 0.35 gap your points are either badly pitted or the fibre heel worn, especially with Tec point

Points are new but they are eBay specials. Didn't think to buy OEM or good quality ones as I purchased the Hondaman ignition unit.

You need to bite the bullet and buy some genuine ones, as you won't or shouldn't be replacing them with the Hondaman system they should last for many years. Make sure you oil the felt pad on the points plate so the heel of the points are lubricated or they'll be the part that wears out the fastest.

Looking on the DS website genuine points for 1-4 and the 2-3 points are £29.95 each. Plus VAT and postage of course, that could be the £2.95 or he could charge the usual £7.95.

I have a few sets, not sure how many, I'll do a pair for £40 plus P&P if that helps.

Cheers ,I'll give it a go with 0.2mm as suggested by Julie to see if there is a position to that will work. If so, I'll give you a shout for those points.

[juitz]

Ok, so got timing to line up between 0.15mm and 0.2mm.

I'll get those OE points but is it possible for the cam to be also worn?

[juitz]

Installing a new starter solenoid but didnt get a wiring diagram. B and M terminals are ok.

But not 100% sure what should go on the 4 spade terminals?

Unlikely to be worn cam, as same geometry (only one lump) that opens either set of points.

The problem is with the geometry in the points themselves, when fitted they should be exactly 180 apart as that is the position of the crankshaft big ends one from another. 
If they can't be adjusted to meet this 180 degree dispersion, there's not much you can do about it but compromise the gap as you've done, or use differently manufactured points that are more accurately manufactured.

Dave I’m going out to the shed in25 mins, just out at the min, can you give us a chance to go home and I’ll call you re solenoid as it’s the same as mine but I’ll do it via video call then easier for you mate. You still on the same number?

Cheers Roo - tied up today but can do tomorrow if thats ok? And yep , still on same number 👍

[Oddjob]

Spare connectors almost certainly are for the starter button connections and the other 2 possibly for the loom so it can get power.

Ok thanks for the info. I'll get in touch with Oddjob as he said he may have some OE to sell.

Good afternoon all!

Have a question on the wiring of the Hondaman transistorised ignition with an m.unit blue.

Can/should/is the black wire from the Hondaman unit is wired to the "ignition" output from the m.unit and teed to the coils?
