my partner 351 chainsaw won't oil the chain?

Hi. Don't know how far you have stripped it down here is a few ideas. Remove bar and chain . Start saw and rev a few times if no oil appears its possible your drive to the pump is stripped. If oil does appear on side casing its a bar fault there is a hole on the bar that lets oil on to the chain .This is blocked clean bar channel and hole.
