Update on the 660 56. Here is the fix for the chain adjuster... I ordered an OEM adjuster, and started having some problems with that one skipping. So I decided to rip it apart to put in the new HO oil pump and try to figure out where the problem was with the adjuster. On the left side of the threaded adjuster rod there is a worm gear and small stud sticking out that rests in a housing in the case. I've seen Walt talk about shimming these things and was going to machine a brass bushing to house the stud and fit snug in the housing. As luck and education would have it, my local (every time I go there I say why do I ever go anywhere else) mom and pop hardware store had the perfect size brass tubing for $1.56... You need to cut a piece off that is slightly longer than the stud and then just sand or file it down to be flush with the end of the stud and stick it back in... Slop is gone and the adjuster works seamlessly. I'll try to attach some photos. Finally put a final tune after break in time and ran the saw on the mill this past weekend. I set the high side at 13,000 and to say that I'm happy is a gross understatement. This thing blows my modified mill saws away. Idles perfect, tons of compression, revs like a 372... Milled up some 22" diameter pine logs to test the original oil pump and this thing doesn't even kniw there is wood getting in the way. I'll try to upload some videos that I took... Stay at it! I'll give a review on the new HO oiler as soon as I can put it back in some wood. I was running a 36" bar and to be honest, I really didn't have a big problem with the way the kit pump was oiling...
