What about the poor SOB who had to buy new equipment due to the incompetence? They are probably pissed!I notice the shops don't really open up the item to accurately diagnose the problem. Some of the best is a Kawasaki ignition came loose and jammed the flywheel. Moved it back and done... if they just turned it by hand and noticed something is hitting something else and it is not inside the motor. Just remove the cover and they would have found the problem and be done in less than 10 minutes.
Stuff like that.
Then again, I got a lot of my toys from shops because of them. Their incompetence fuel my guilty pleasure....
