Not so quick son.
So far I've Changed the plug for a new one (gap checked) disconnected the SS switch,(eliminates the possibility of that) slung a good squirt of carb cleaner through it, checked the usual connectors.
it will start but then it stalls, almost like the ignition is failing, seems tickover is low but won't adjust any better via the mix screw (as per the yammie manual)
I suppose I'll spend tomorrow stripping it to check the coil resistances, and possibly stripping and cleaning the carb out, but It seems like electrical to me.
I'm open to ideas tho :dunno:
I'm thinking it can't be anything too serious or it wouldn't start
