It not that I won't look at them as much as it normally cost more than replacement cost to repair them. My current labor is $40 / Hr which is about half of many local brick and mortar shops. Even then cost to much to charge one hour for two to three work plus parts. Most the cheap bent shafts are selling at Wal-mart for $75; just not economical to repair. I will talk to the customer and explain things. There are few times that they are will to repair the trimmer anyway. I had customer it was the only trimmer his wife could operate for he already tried another trimmer her to used. That one I did at parts cost only and it still ran close to $45.00 on a $75 trimmer.
And Gadge you're right about most guys not even near being a repairman anymore. I love it when they spend a lot money and can't fix the problem then it shows up in my shop and I repair a faulty .50 electrical connection or something just as simple.
