If the oil is OK, I mean not full of water or gas, I do not like changing it or the filter due to "losing" the prime.. A new filter could give you ZERO oil pressure for a fairly long time, especially if you get a air lock in it... JUst my opinion..

BAD fuel is gonna be your biggest headache on first start..

If you just want to see if it starts why change out all the points, plugs etc?? YES do this eventually but not at first.. IF it doesn't start THEN start to diagnose....
