I like to break everything down into components.
1. motor - does it turn ever easily by hand?
2. battery - you said it was new?
3. start solenoid - maybe bad inside, you can rebuild or replace
4. starter - new also?
5. wires/cables to and from the start solenoid to both battery and starter.
That's all the pieces to the starting circuit. So it looks like maybe the start solenoid is the best bet?
Another thought, what weight oil?
