Agreed. You will never find one that "needs nothing". They are selling it for a reason. 9 times out of 10 its because there is something wrong with it, it runs crappy, it needs TLC, they're sick of fixing it, or they've made a temporary fix they know won't last.
If you buy a 2-stroke used, you MUST go through it. With the FL350, there is 29yrs of potential abuse, neglect, skillbilly work, and wrong-doings that can accumulate.
A complete non-running FL350 in decent shape (not a total rust bucket) is worth $1200-$1500
A complete runner in okay shape...$1500-$2200
A complete runner in great shape...$2000-$3500
A complete runner in great shape with goodies + spare parts...$3500-???
Just parts...at will-sell-prices...the things are worth $1200-$2000 depending on condition...
