Hey Stu! There are a few of us on this group riding A10’s a few thousands km north of you in Kenya … I do occasionally and sometimes have to buy spares from the UK, although generally I find most of what I need locally and I’d recommend not getting too fixated on getting everything from the UK.. I’ve use NGK BP6E plugs and they have been super reliable and available in Kenya .. I can’t remember when I last changed them..I just clean them on a regular basis and they keep going.
From what you’re describing and others have eluded to it, it sounds like you have a number of combined issues going on… If you have a spark and fuel in the cylinders you should get a result.. so in the absence of anything, check the static timing, tappets etc first. The easiest way is to put the bike on the centre stand, remove the plugs then rotate the rear wheel in a forward direction until you find TDC on the compression stroke.. A chop stick or something else that’s soft but won’t break down the plug hole will tell you exactly where TDC is… if your static timing is correct and the valves are set, back the rear wheel up so whatever you have in the plug hole drops by about 11mm / 1/3 of in inch (someone here will have the exact measurement) then check your mag timing.
Its easy to the make the mistake and time the mag after TDC rather than before..I’ve done and it ate my head for days… once you know all that is set correctly, you should get it firing.. and you can move onto sorting the carb.
The main reason my A10 runs are the guys on this forum. There’s always someone awake somewhere in the world who’s there to help. I knew very little about my bike when I started and the generosity of information on this group is invaluable.. just keep asking and your bike will be running before you know it,
Guy
