UK 500 fixer upper

After starting to go off topic on other threads I thought I’d best start a proper build one..
As bought;
Dunstall exhaust, carbs properly cleaned from this state
Sourced a tank...
Gave it a once over for now with Rostio and cellulose Porsche Conda Green
After rebuilding the carbs, cleaning the entire fuel system, replacing a bodge points plate with a good used one, still wouldn’t run or even start. Pulled the plugs and put the used ones that were in the tool tray back in and off she went! No4 cyl still not playing ball but I can hear a stray spark under the tank, so checking the HT leads as soon as I can cobble up a temporary tank - I’ve drained the 750 tank and I’m waiting for the Rostio enamel to dry..
It has been buggered about with in the recent past, cheap Chinese points self tapped into the plate, crimps on the LT leads, possibly wrong coil, definitely wrong plugs! Loads of iffy wiring to be sorted. Just trying to get it running reliably, enjoy a few rides over the summer then plan the works over the winter.

All the caps are straight so I’ll look into getting the right ones thanks. I think the stray spark is actually a leaking down pipe seal, I’ve just nipped them up by hand with a 3/8 drive small ratchet and guess what another stud has snapped! Eight more ordered....

I noticed the throttle doesn’t snap back, just pulls back to the stop. I’ve tried to smooth the cable route but what else can I do?
