Chainsaw Repair

Dug out some pics of old reliable. Thanks to its quality  European parts that kept it going this long, Chinese parts would have whimpered out ages ago.
Notice the Oregon 50AL chain........404 chisel bit chain in .050
 Now how rare is that chain?           Still got about 30 or more feet of it on the roll.

As I said earlier my 066's cylinder has never been removed which says it's bottom end is still good too.

This 066 had a life of mainly cutting spruce and tamarack  lumber with a 36" Alaskan sawmill. Also equally  years of bucking and noddle splitting birch firewood, working in temperatures from as high as 110 to -40 below F.
This is a 066 Magnum Artic with the heated carb to keep it running at -40 below, nothing harder on equipment then the cold with snow thrown in
It has a built in thermostat that keeps the carb a constant 77F temperature. Last time I checked this 23 year old saw's heating element still works.
 

All AM. I just got a 56mm top end as well and the casting actually looks pretty good. There is some casting related roughness on the "sharper" edges of the ports, but my bet is it works pretty well. Maybe a mildly tweaked 56mm dia top end on one of those AM bottom ends to see if it can handle some abuse? The piston in the kit looks really good as compared to other AM offering's. The wall thickness is there and uniform. And the rubber parts that came with look a lot better than their Husqvarna counterparts.... this might be interesting. Going to build up a second one in the 56mm BB configuration ... then run it vs. that first one and also with my bud's 661.

$135 on ebay.... I bid on one as well. hoping for under 100 delivered
