Just last week my 7 yr old silver series LB did the same, no spark. You
need the coil-ignition-plug wire, module apx 40$, the plug wire is
integral, coil and ignition module all in one, its about a 30 minute job
to replace, You will need a spacer to properly gauge the closeness of
the coil. It should be 110mm? the thickness of cigarette hard pack
cardboard, ask at a dealer.
