Now where do I go?

Poulan "Weed Eater" HD12538F won't start!?

Son rode mower next door to mow "Grans ma's" yard and mower died. Poulan "Weed Eater" HD12538F riding mower won't start!
Checked 30 amp fuse = good. I replaced the solenoid [ no sound from it (part #145673)]. After replacing solenoid, the motor tried to start, but killed the battey! Battery (12v, 25 amp) would not hold charge, so I replaced it. Motor stills tries to start by doing a 1/4 turn then 1 1/2 turn, but won't! 6 Ga. cable from solenoid to starter gets "hot" after 4 -5 tries. Do I need a new stater, or is there something else?

Since last post (Aug.) I have drained the fuel tank, cleaned ALL fuel lines replaced fuel filter (made sure of propper direction for flow) and added with fresh fuel. Replaced spark plug.

Egine still goes through atempt to start (as if deprived of fuel), but won't!
