I ordered a reverse cable from you guys, got it installed and when i pull the lever, which is super tight, nothing happens. I’ve tried moving the kart and everything. So, i took the housing off and pulled the pin where the cable slips in, and started my Maxxam 150 2r. The engine revved up and wanted to go backwards so i shut it off. I know that the reverse will engage but it is super stiff and gets even more stiff when the go kart is running.
