Report "4 inch from frame while having son turn key over and It had nice spark? did the same to each plug wire and all sparked?? so im kind of lost as to what it could be? My only other thought was timing issue or skipped timing but this model has a chain(not belt)also I didnt see how that would have happend from just sitting....I thought mabee old fuel but it started fine and ran good last time we drove it 4-months ago! So im out of things to look at and could use some additinal advise or pointers at this point. thanks in advance for any help"
