Some news........ The mustang goes very well surprisingly!
The starter must be warn. I have to pull it slowly until I feel it engage and then start it like a normal mower.... Or is this a normal feature of the top mount starter?

The mower is one for the collection I think and to occasionally mow the lawn with.

The pawls swing out as they should. I thought the bucket might be warn. I did clean it with some fine sandpaper.
