I like messing with old Karts myself, Besides having a part time job at our local putt-putt/ go-kart track, maintaining the concession type Karts, Ive had a small engine repair business in my shop out back for quite sometime,which has pretty much turned into motorcycle repair now.Ive found that word of mouth advertising has proven itself time and time again.If im needing a kart frame or an old roto-tiller engine to (prefer 5hp briggs dual bearing blocks) I simply begin to ask around. I have one frame I need to pick up thats on top of a guys shed and theres a pile of old briggs stuff an old fella was throwing out(2 of which were single bearing blocks. I often run ads in our local shopper for old motorcycles, Karts, Mowers and parts. Most folks cant wait to have somebody come by and get there junk and just give it away. Someone I dont even know called my wife the other nite and would like an old Honda 350 removed from his garage, just come and get it. I got er hittin on all 4 but needs work. So you see good things come to those that wait, simply by telling folks what your looking for. If your from the Atlanta area, Ill give you a frame, just come on over and pick one out.Got lots of engines and parts, Too. Have fun and dont red line.
