well I will buy the correct plug tomorrow when I go to town, but I have serviced every part of the ign system, right down to the actual key switch and it is really a wonder it worked at all given the corrosion on all contacts. the reverse limiter was the worst
so I am thinking I must surely have fixed the problem and get way better spark, well that's assuming I replaced all wires in correct place.
but main issue is the brake line from the master cylinder needs replacing. Any hints on getting one second hand, delivering to Australia.

I just started having similar problems with my 95 Sportsman 400 (2 stroke). I was plowing the driveway and it kind of sputtered and died. Would not start all the way to the point that I killed the battery. I recharged the battery and changed the plug. It still wouldn't start... for a few minutes, and then it finally sputtered and started. I ran it for about 2 minutes (finishing up the plowing) and it died again... same thing, won't start again. It usually starts right up when it is cold. I am not convinced it is a "when hot" problem, but I'll try again once it is completely cooled off.
I did turn it over with the plug out and didn't see a spark (with new plug or old), but that was before I finally got it to start again after putting the new plug in, so either I just can't see (it is very sunny, could have missed it), or the spark "comes and goes".
Any ideas? I'll probably stop somewhere and get a new plug cap while I'm out today, but other than that, any advice? By the way, the reverse limiter is already disconnected, so that's not it.

I guess you know the plug must be earthed when out of the engine - I use a starter jump lead, one end around plug and other clipped to a good earth point on bike
This is where the spark looks sort of weak to me, but I havn't got any further
as Old Tech suggested I need to get a manual and test some ohms
