G'day Lockstock and nath

Yes I just thought the spring was slipping off because of the first images and mentioning the tang.

If the starter is not turning the motor over it can be a starter pawl problem as it does look a little worn,
I'm not a fan of starters with only one pawl if it was me repairing this I would still replace the starter and
starter cup if the original cup won't suit the new starter ,I've googled Honda HRU 194 starter pawl and haven't
found any for sale.

Cheers
Max.
