Hello tiger,
The starter only has one pawl that throws out.

There is no primer on this engine, it has a choke.

Try this thread, it will give you some idea of what your up against.

The manual for this engine is on this site and available on the web.
cheers

Happy is he who penetrates the mystery of things.
