Tim, that is one fine looking Canadian 4000! A 4000 with a chain brake is one of my favorite saws to run and collect. I would like to ask how common chain brakes are in your neck of the woods, as they appear to be a Canadian staple: are they easily found, or do you have to search them out? Bob AKA "Redunshee" and I traded drive covers a year or so back in this sticky, and I now have two 4000's with chain brakes. I also a have Poulan Pro 375 which I equipped with a NOS 395 Chain Brake kit I purchased off of eBay within the past few months. That's like the Super Bowl of 4000's right there! Best, Max.
