Last Saturday helped bud take down about a dozen trees on his new property. Pulled out the 372xp with 24" bar for bucking a big one. After a few cuts bar and chain are smoking like mad and untouchable. Its throwing oil so I put it aside and spend the day with the 353. Have to admit I've been using the 353 almost exclusively for a couple of years as its way more manageable weight wise.
Anyway, couldn't recall how old the bar was and decided to pick up new. Put in an order to Baileys but decided I didn't want to wait so picked up a 20" genuine Husqy HT 380-72 bar at the local dealer this week. Then decided no point in using one of my old chains, threw a new semi chisel on that to boot. Been running WPL 20 30SC72 on it for some time and that is what I used. Bar is correct and a match .050" and 3/8".
Cleaned saw up nice and applied new bar and chain. Went back to buds today to finish bucking the trees and about ten cuts into a red oak today it started behaving badly again. Stopped using it right away until I could diagnose it further and ran the 353 again for the rest of the day.
Its throwing oil, so I removed the bar and chain and verify its pumping properly, yes. I use Tractor Supply bar oil and pretty much have for the 7 or 8 years I've run this saw without issue. I've read through a number of threads on this topic, which all seem to point to lubrication if the bar was in good order and matched the chain. Since replacing the bar and chain did not change the behavior, I can only think oiling, but that seems okay.
Another interesting data point is that the chain is not dull, and the removed 24" chain isn't really dull either. Anyone have any ideas for me?
