I am running a 3120xp as a dedicated milling saw with an alaskan mill. I have been running it here and there over the last 3 years when I picked it up used with a 60" mill set up that was unused other than the frame. I also got a 48" cannon bar with it which had been barely used and an ugly 32" bar. The guy I bought it from said it had very little use and saw was real clean and to my untrained eye looked like it was in top shape. I have since found some signs he may have BSed me. Zip tie on throttle cable to secure it on filter cable and missing screen in carb.
The saw was doing great until the last few times I have used it and it is over heating really bad and quickly. The first time it happened was when I was running the 24" bar and chain from my 372xp to mill smaller logs I changed out the rim sprocket to match pitch.
I assumed the smaller bar was the problem but now it happens no matter what bar I run on it. I am using the ripping chain from baileys with out any modification and running fuel mix 50:1 and also using auxiliary oiler.
I have been searching all over for answers and from what I read think it may be A) intermittent oiler B) should be running richer mix C) saw is running lean
Here's why
A) when turning chain by hand on the bar it runs freely for a little then has some resistance back to running freely and back to resistance over and over and same goes with chain off just rotating clutch with my hand.
B) just from what I have read on other threads.
C) same day I milled with smaller bar my friend adjusted carb settings because saw would die out when idling. Also responses to other posts regarding over heating saws
Is the oil pump on it's way out or damaged from over heating caused by another problem?
Any advice on how to figure out whats going on would be awesome. Thanks in advance
