Hey Vonmighty
Don't get pissed off - it is nowt - we'll suss it. I'd go further than Mike in that if your local bike shop needs a manual to fix this bike take it to the bloody bakers, coz they know more!
If you have no spark it can only be a limited number of things
first off download Mikes wiring diagram- then blow it up as big as you can and get some highlighter pens colour back the wires from the coil appropriately - then look at the wiring on your bike for any loose connectors/broken wires etc - This is what I did when I fitted my new CDI unit and had no spark - it was a loose connector into the new unit, one prod later and it all worked.
Personally I'd disconnect the side stand switch - follow wire up and pull the plug under the seat - sack of shit idea by saftey nazis. ( same for clutch switch)
If you can't find any thing amiss it may be components that are faulty but there are only three suspects - coil and HT lead, CDI unit and trigger on crank for CDI - The only one I am not familiar with is the trigger - but I will be tomorrow when I've had a look!
Just a thought - tracing your thread back - did you leave the bike switched on when the battery went flat? And is you battery fully charged and holding that charge?
These bikes are simple machines - for what they cost it is worth messing and learning from them - knowledge is priceless so be happy that you are getting a cheap education!
Besides, if you spend a few months learning you could open 'Vonmighty's BIke Shop Alice Springs' 'coz you ain't got no fucking competition!!
If it turns out that your CDI is goosed I'll send you my standard one (unused!) and you can buy me a pint when I'm passing through...
This is not meant to sound clever, but I started dicking about with a BSA 350 when I was seventeen - a very similar engine in a lot of respects (but shit) - and, $4% years on, I'd not be afraid to dismantle and rebuild any bike, hopefully to a high standard - You'll get there mate - just keep at it and keep asking questions
