Hello,
I have a Jonsered 670 Super with a 24" bar on it. Does this have enough power to run an Alaskan chainsaw mill? I have an oak log and a few Madrone logs i'd like to cut into boards.
 
That saw would do the job. Not as fast as others, but do it all the same. I have a friend that mills with an old stihl 038 super, which is basically the same size as your jonsered, and he has cut a lot of boards with it. Those old jonsereds are tough enough for hard work too.
 
Thank you all. I was able to make the guide cut and one more slab before the saw died. I'm hoping it's just because the saw has not been running for awhile before using it this time, and hadn't had any extra tuning. I haven't had a chance to look at it closer yet.

What do you mean by died? Can you still turn it over? If not that does not sound good. Proper tuning is essential but I hope it was not that.

I tried to start it today and the pull cord won't fully extend. It will only fully extend when I pull the pulley slowly. Any ideas what could be wrong?

IMG_20171119_134041.jpg This is an example of what I started milling posts from smaller diameter logs several years ago. We mostly start where we are, and have experience teach us. I still use the combo pictured for edging or cutting from inside a larger slab milled with the ms-460 in my avatar or the 661 that sings a great tune in the cut with correct feed rate. Check or have checked the pressure/vacuum in your power head to be sure it's in good order, clean the air filter, check the fuel filter. Inexpensive care for a tool that has a habit of being expensive to rebuild or replace. Match the chain to the power and length of the bar. The combo in my avatar is sixty inch bar with skip chisel chain pulled around it. Half as many cutters reduced the power required but still slowed the feed rate to keep the power head singing rather than bogging down in the cut.
A few days milling will teach you more about what works best for you, til you learn more! Reading milling 101 is worth the effort
Stay safe and enjoy y'all
 
You really need to get into a 90cc plus saw to do any kind of milling. You are just gonna wreck a good 670 trying to mill with it.

Thank you for the advice, I will check these things and do a little tune up. Hopefully that does the trick! I think I'll definitely start looking for a larger saw as well.
