Stihl MS 260 Chainsaw Oil Going Behind Plate Instead of Onto Chain

I have an MS 260 chain saw with a 16 inch bar. I borrowed the saw from my dad and the chain and bar were badly worn out so I replaced them. Things were going great for the duration of time I've had the saw until i noticed things smoking one day. I thought I was out of oil but I wasn't. I noticed the chain was dry. Usually it had oil on it. So I took off the bar and chain and made sure the oil hole wasn't clogged and wiped down the area around it. Behind the bar is that metal plate where that covers the area the bolts protrude out of with the oiler on top and a slit in the plate for oil to come out. I took it off and wiped everything down. I put the plate back on.

The saw was still smoking and just wouldn't cut. I've manually oiled the chain and it seems to do better but it dries up so quick I can't tell if it is helping.

I took the bar and chain off and ran the saw to watch if oil would come out. What is happening is the oil is dripping down behind that metal plate instead of down that little channel onto my chain. The metal pate has that slit in it for oil to come out. Well the plate kind of overhangs the channel. So oil can kind of pool in between that channel and plate. The plate is tight though. Now I can't seem to get that screw holding it in place out to check behind it again. The screw comes out a bit and then just spins and spin and spins. It isn't stripped either.

Any idea why oil is going behind that plate and not onto the chain? Such an annoying problem when the saw runs so well other than that and I just don't have a ton of time to devote to figuring it out.

Thanks.
