Burnt up sprocket nose on a new 42" bar

That would be a contributing factor.
I would suggest using a lower viscosity bar lube.
If you are manually pumping oil and have the output opened to maximum your oil tank should be close to empty when the fuel tank is empty.
Without the manual pump it should be down to at least 1/3 from being empty.
I don't like the little oil holes on Oregon bars and opening up the supply holes may also benefit the cause.
 
Ok so after some investigating and talking with Roland from Treestuff, turns out a bunch of bars were sent out from the factory with the wrong sprocket bar tips!!! They put .058 gauge sprockets on .063 bars! Problem solved, Luke and Roland took great care of me as usual!
 
What clued me in Devon was that the entire sprocket area of the tip was burnt, but none of the bar was burnt. If it was an oiling problem or such, the bar would be showing signs, but since it was fine, it indicated the problem lay with the tip.

That's interesting because I believe the nose sprockets are universal for all gauges.

Sorry Devon, but Kevin is right: that's a pitch problem (the average length of each chain link, calculated by measuring the distance between any 3 chain rivets and dividing by two) Those drive links are too far apart for that sprocket, so it looks like you have a .404 chain on a 3/8" sprocket. Gauge is how wide the slot in the bar is that the drive links ride in.

I never would have guessed that Kevin, but went out and looked at all of my replaceable tips: All stamped 3/8" pitch, but no gauge markings. Are you saying they're all wide enough for .063 gauge, and the extra slop from a .058 or .050 doesn't matter because they're under tension and just riding around the tip on the sprocket? Interesting. Well, I've learned something - time to call it a day!
 
Yeah they made that mistake also putting a 3/8 sprocket on a .404 bar! What a mess !!! Must of been a Friday afternoon or
Monday morning job ! Over all big whoopsie at the Oregon site the bar clearly is stamped and what's on the tip is totally opposite !

Oh, wow! The problems are much worse than I realized. Must be some hard drinking going on near the Oregon factory.:birra::loco::confused::vomito:
