I picked up a Husky 394 with a cracked case. Its not in the crank case but looks to be an important part of the saw structure. I thought about trying my luck brazing it? Otherwise try JB weld? Or leave it as is? Or the last option, finding a new case or halve? What do you guys think? Has anyone brazed magnesium? Or had good luck with JB weld on cracks like this?
