This machine was given to me. I'm a female that doesn't mind getting dirty so I do a lot of my own repair work. Old bolens 30" rear engine rider Model number 283707. I have looked every where on line and can't find to much info on this machine since it is an 80's something model.. I rebuilt the carb. The choke link is bent on an angle with a long U shaped loop on the end that goes behind the housing the thorttle cable connects to. It was off behind the housing before I started. I can not find where this rod connects. It starts fine but runs wide open. The throttle does not move when I move the lever up or down located on the front of mower. The cable clamp is tight. I can keep it running at a normal speed as long as I hold the throttle lever that goes in the carb. Any help would be greatly appreciated.
