I have a Sugi Hara 20 inch and a Sugi Hara 24 inch bar for my 372XP. Both bars have the small slanted oiler hole that we see on Oregon Bars now. The problem is that the hole in the bar will get stopped up after about 5 minutes of cutting. Both bars are new and I now just keep a oil squirt can with me to keep the bars oiled, but I need to replace them with one that works right. Anybody here have a problem like this? I know I could buy Husqvarna bars, but I think they are made by Oregon, and if so, I will likely end up with the tiny slanted holes that will clog up too. Thanks for any help.
