Here's some of my random buying tips:
If your not already, use craiglist's search box with each one of these spelling terms: gocart, go cart, gokart and go kart.
Also try to do these searches as often as you can and have your cash all ready to go.
Around here when a trully smokin deal pops up it'll usualy get snapped up super fast. I've noticed many times the seller will either edit their ad as being sold or delete it. (sometimes only within an hour or so of it origanaly being posted)
It seems like lots of potental buyers tend to ignore the C/L ads without pics, many times these ads also have hardly any meaningful info posted. These types of ads can work to your advantage cutting down on your buying competition if your willing to spend the time contacting the sellers requesting pics and/or better yet going out to see if its really a deal or not.
You could also start searching all the C/L's from the other towns you might be willing to drive to for a trully smokin deal. (you'll also get a better Idea of what a bargain is by researching through as many kart ads as you can dig up)
Try doing the google search: for sale (and then all the go kart spellings) and then type in your state. This should find you serveral online ads besides craigslist.
Also try posting your own "Go kart Wanted" ad. I've had really good luck buying all kinds of stuff with my own Wanted ads, It seems to trigger people to quickly sell something off without having to deal with posting their own ad.
Good luck in your quest, keep looking you'll find yer deal
