Capacitor Discharge Ignition CDI Module Tecumseh 3.5 two cycle

No decal label on the Vacuum / Shredder 3.5 HP Tecumseh LAV two cycle engine.

Circa approx 1975- 1985 ???

Trying to replace the ignition trigger ( CDI) .

Only markings are : "Tecumseh 4 340 ".

Can anyone help me ID the replacement part number / vendor ?

Are there updated replacement units available?
