Well, perhaps it is a rich stall but setting it up as above will ensure you've got it pretty much correct. But be realistic in that you're using 30 year old technology and 2 strokes of that era were not always as sweet as they might be.
The difficult hot starting may be a different issue - first stop for that is a hot cylinder compression check.
