I just acquired a Mcculloch 610 Pro Mac at a yard sale. What I noticed from the get go is that the saw was upside down and the brake was always engaged. So I removed the saw, cleaned out the carb and it fired right up. So far so good. However, when I reassembled I noticed the brake is always engaged. My guess is that the brake spring is not properly installed. So I disengaged it, and now the spring is loose and saw has no brakes at all. Based on the diagrams I have seen of this saw, the brake spring is facing the correct way. I am just not sure where the ends should go. See picture here.
My guess is that I need to somehow push the L-shaped end of the spring into the brake lever notch. That would hold the brake in the off position as the "default" position and would come off the "off" position when I manually move it.
Anybody have any ideas as to what I should do. I have considered using it without a brake but I feel that would be a safety issue (especially with a rookie like myself.)
Thanx in advance.
ps. Also, some of you may disagree, but I find this unit to have more humph than my Stihl MS250.
