Need help with JD 345 anyone here in New Bern, NC

[scarab280ze]

Just inherited a John Deere 345 and it hasn't run in awhile and didn't turn over so I just bought a new ignition switch and a delay relay off ebay and waiting for them to get here. while I'm waiting I thought I would see if there was a area that was prone to problems on the 345 soI can get a head start on it? serial number is above 070001 if that is of any help. Thanks
