I have a 1984 Yamaha QT-50, and the spark plug cable (a.k.a. high-tension lead wire) is loose and does not always stay connected to the spark plug fitting. I believe this is the reason that my moped stalls about every 5 seconds.
The parts dealer tells me that in order to fix the cable I will have to replace the cable and the ignition coil ($65).
Can I somehow fix the cable (prevent it from loosing connection to the spark plug) without buying a whole new cable and coil?
