Hi all (sorry if in the wrong category)

any ideas please .....the machine was driving along nicely and just cut out and ground to a halt ...now there is plenty of fuel ..ignition lights and electricals like horn ..indicators..work ....but the starter switch does not re fire the engine (nothing) ....with a car battery and a long screw driver and the ignition on and the machine in neutral i bypass the switch and short straight to the starter + the engine turns over but will not fire ..or start....i have at this point have no more information to put forward ...other than i went through all the basic checks i could in the field like fuse checks and all are ok ....i turned the engine over repeatedly but noticed no smell of fuel (un burned) ...i blew into and pressurised the tank (to attempted to push fuel thro ...but nothing ...not even a splutter...  i haven't had chance to strip the machine down yet ....so just asking for pointers or if anyone had the same nd fixed it

Kindest Regards Neil
