JB Weld could be an option. I think I'd try to bend a thin strip of metal over the post then drill and pin/screw through it.

Are they from a Boyer kit ?
If they are then they should have + and - marked near the terminals.
Can you also post a pic of them mounted as I'm not really happy with how I've mounted mine.

I don't have another set of carbs to try, I might have to lookout for a set if setting the timing doesn't sort it. I'm reluctant to throw more money at the bike though, I keep saying I'll never buy another vehicle that isn't already in regular use as they're always a pain to get sorted but I keep buying them.

I set the tappets when I first bought it 350 miles ago, could they cause these symptoms?
The Boyer system I've fitted is "KIT00289 Micropower ignition system for Honda "4" S.O.H.C. Motorcycles". Fitting is as you describe but it does not tell you to grind off the raised bits, timing instructions tell you to line it up the magnets with the posts at TDC then time with a strobe to max timing marks at 4,500rpm. I've ordered a new strobe as mine just wasn't clear enough and kept giving me shocks, but I'm not convinced that setting the timing will fix it.

I've fitted a Boyer ignition kit, but I'm struggling to time it. The instructions say time to the max advance marks at 4,500 rpm. My strobe is normally clear enough to use at idle but it doesn't seem to be able to cope at that high an RPM, and also gives you a shock every time you touch a metal part of the bike once over around 3,000 which makes fine adjustments tricky. I've borrowed a bottle of tipex from work to highlight the markers, if I still can't see them I'll have to take it to someone or buy a new strobe. (although I think I need a new strobe anyway)
A quick test ride shows that it hasn't resolved the problem, it's still bogging at 5,000rpm and being inconsistent above it, although that may be down to the timing.
Cheers

No, I didn't trust cheap ones to be calibrated correctly or want to pay for expensive ones so I took a chance on a simple device off ebay, I can't link to it now as it's blocked at work but it's essentially some clear tube and some ball bearings. It's workings seemed pretty logical to me and it was quite sensitive so I'm reasonably confident that it will of done the job.
In the upper rev range it kind of splutters and surges and exhaust note goes flat.
I'm considering upgrading to a Boyer Bransden Micro Power Ignition system. On another forum the coils and the mechanical advance have both been named as possible sources and this system would replace both.

I found that the feed to the coils had a corroded connection, after cleaning that up and syncing the carbs I've only had a short test ride. It feels allot better but it doesn't pull cleanly from 5,000 up over although in 4th or lower it will still rev to at least 8,000, in 5th it runs out of steam at 80mph.
The fuel filter is still clean.

Few miles East of Durham.

check the pipes heat up evenly, when mine did this it was a blocked pilot.

Maybe mine has a self preservation device, I had to cover 150 miles before it allowed me to ride enthusiastically.
The filter I've fitted is rather small but it's what looks like a sintered metal rather than paper element. I've found these flow very well for a small size and don't block easily, they probably don't filter all that well either but will hopefully catch anything big enough to block a jet.

No I haven't but I have a tester somewhere so I'll dig it out.
Since the last carb clean mines been a good starter hot or cold and it's also oil tight, but the test might highlight some other issue.

I use it to get to work when the weather's nice and also do one or two of the many organised runs.
Mines just a Chinese z50 copy running a 120 engine.

My patience is starting to wear a bit thin with it.
Once it's sorted it's going to take me a while to build up enough confidence in it to go any distance which is a shame as this was supposed to be my distance bike with the monkeybike staying in use for local rides.

I'm hoping that's all it was, the queue was quite long, I'll see what it's like when I next ride it.
The filters easier to clean than the carbs :-)

I stripped the carbs, found a blocked main on number 2, a blocked pilot on number 4 and float heights a bit out. Also fitted a fuel filter, checked the timing with a strobe and fitted a working oil pressure switch.
It ran like crap at first then sorted itself out and was fine for an hour but lost all power just as I was arriving home - This was after sitting in a traffic queue for some time.
