Hi all

My Cota 310 (1990) used to run fine and now it does not spark. Does anyone have a wiring diagram (that I can get a copy of)

And any common faults or ideas?

Thanks

Simon

IF your 310 is still stock original, electricity is initially produced by the magneto flywheel magnets passing by a coil and that coil can be tested for continuity, provided the coil has not failed your spark is controlled by breaker points that would be highly suspect if the coil tests good, in close proximity to the breaker points is a condenser which is also a component that is known to fail with age.  This all powers the ignition coil, plug wire, cap and spark plug which are all subject to failure although not as likely to fail as the previous noted items.
