[Healeys] "Engine making a weird noise"

[Richard J. Hockert]

'Making a weird noise' is challenging to analyze.
Flat battery 90% sure has been correctly diagnosed as charging system failure- check generator, regulator and wiring loom.

Second issue of low revving - check  1. exhaust is free flowing 2. Fuel flow is not restricted 3. Distributor is advancing and Petronix has correct curve


Best regards,
Jim
