That doesn't sound as if it is spinning over fast enough.What is the problem?
I'm going to service the starter, thanks for the help.🙏That doesn't sound as if it is spinning over fast enough.
Could be a lazy starter, faulty battery, bad connections, may even be the alternator not charging enough to keep the battery fully charged.
It sounds as if there is plenty of compression, so the valve clearances are probably not the problem.
