clacking noise

[Turkj40]

has anyone had an issue with a clacking noise happing right as the motor fires up. i replaced the starter on my SB motor and though i had broken teeth on the flywheel, after inspection definitely no broken teeth. Sounds like arching so maybe a bad coil pack? any thoughts before I start throwing parts. also not internal, once the motor starts she runs as she should.

Arching may be bad plug wires which in turns causes a misfire which in turn causes the flywheel damper plate to rattle. Make sure the engine is running on all cylinders and the rattle will most likely disappear.

Do you mean like lifter rattle before the oil gets pumped up?

not a rattle or a grinding, more like two wooden spoons slapping together twice

do you have Hurth Transmissions? Port side will clank....common issue and the fix is to replace tran oil with 10-30
