hi everyone,
                    thanks for all the advice,just an update,got the gear wheel and springs but was finding it hard to get the gear wheel rivets,until after a few hours on the internet found this

https://sites.google.com/site/priorymagnetos/magneto-atd-spares

so have the kit and a spare set of rivets, £19 for the kit and £6 for the extra rivets (to give me one complete spare set) not a bad price i thought and you also get full instruction with photos! and the last bit of the instructions tells you to go down the pub! honest.
 Not sure why the teeth stripped off the wheel yet ,as i have only taken off the outer timing case to remove the atd.The magneto was full rebuilt before fitting by the "magneto guys" although i never rebuilt the atd ,so i am hoping it just stripped due to its age ,should hopefully find out more at the weekend.

My Flash had a couple of adjacent teeth broken when I got it, not entirely off but couldn't have been meshing by much.

Fancy finding that website - rings a bell or two here ;)

Yeah. Got a VP in the office here who's really good at giving up smoking. He does it most years.

hi,
    well got the parts,and fixed the atd.had a little trouble setting the timing up though,it seems i was setting the right hand cylinder up with the top cam on the mag and not the bottom one!.
    Cleaned out the inner timing case but no parts of the missing /worn teeth were found.Changed the oil and cleaned out oil tank filter.
    The bike started first kick! ,great i thought,got the top off the oil tank and checked the oil return.It had just started to spit oil back when the engine just stopped,tried to restart it but............................it had seized!(less than a minute running)
    I can only guess that parts of the old fiber gear must have blocked some thing in the oil system? so looks like an engine rebuild at least.Got to finish my rebuild of my suzuki ts 250 er first to give me some room in the shed.
  So i guess thats the end of this summers bsa riding.
Like i said before .....the joys of vintage bikes!  *sad2*

Another Bugga tale. I can't see how a bit of tuffnol swarf could cause that. It may block the gauze over the sump plate or even cover a bush dribble feed hole, but to cause a lock up  *????*
Good luck.

Oh Dear!
I spent a few days asking everyone I could think of that might know whether I should clean out the trap change the oil and install a new fibre gear or strip the engine... I stripped the engine; still in pieces but I'm glad I did it (Thanks Musky) I found fibre bits everywhere except the sludge trap!

Wassell ones are absolutely fine. I use them all the time.

That line doesn't sound like a very good advert for Wassell!! ;)
I don't understand the comment above as I have repaired dozens of ATD's and supplied dozens of happy customers with my ATD repair kits. All four of my A10's have Wassells fibre gears and I've never had a problem with them. Sorry, just feeling a bit narked........

I got that one beeermacc  (meaning if they were good you only use them once - relevant if you had just one bike)), but since you brought it up I suddenly realised Cyclobutch's remark about a CEO in his office giving up smoking (finds it easy does it all the time) was maybe in the wrong thread, I couldn't understand how that was relevant in the thread it was in  :!

hi,
    well finally got round to having a look at the engine at last! .Although it will now turn over i didn`t want to try to run it again as i was sure it would seize up again when it got a little warm.
    I was not sure what to do next now that it will turn over,so still with the thought of blocked sludge trap/oil ways i decided that the only course of action was to take out the engine and fully strip it down.This was the only thing to do to put my mind at rest.
And thinking that there would be no more riding weather this side of next easter!.

Well the following weekend the engine was fully stripped ,washed and blown out with an air line ,crank sludge traps removed etc.The sludge traps were clear and the oil way all seemed clear,the only seized/tight part was the steel breather "top hat bit" in to the inner alloy timing case!.
I know if you fit a cork gasket thats too thick behind it and tighten up the timing case it will be enough to stop you turning over the engine .I have done this before ,and posted the results on this forum! i ended up with an home made cardboard gasket under the cork one to get a nice fit and stop the oil leaks.I have run like this for a few hundred miles before the breakdown.
So just before i put it all back together (breather hole in the timing case all cleaned an polished up) has any body else had this kind of problem before?

ps. both bores,pistons and rings ok

Any comments before i start to rebuild welcome 

Cheers Rob

( I think) I did the same thing, but used gasket paper- so far so good, ~5K miles.
 Only thing I can think of is the cardboard might've swollen...? especially if it was a cereal box... *conf*

I remember this below- picked up on GB straight way, thought it funny but let it ride, it's the kinda crap thing I'd say- was probably peeved that GB beat me to it.... *smile*
