howdy joe !
just slow down to a gallop sir !
there are to my mind four problems with the starter clutch ,
first have a read of biques thread , mechanical , starter clutch warning and just take time to figure it out …
but alternately if everything else checks out ,
1. there is not enough charge in the battery .
2. the brushes in the starter are worn , ?30 for a refurb kit .
3. the gear and pinion wheels are clogged full of old grease .
4. the rollers , plugs and springs are worn , ?36 fora refurb kit .
a bench test of the starter motor out of situ might help a diagnosis ?
only as you’d need to remove engine covers to figure it out ,
best to coincide this with an oil change …
any other ideas folks ??
