i have a 28mm oko carb and i cant keep the throttle cable from falling off. i can run the cable thru the spring and into the plastic holder on the end but when i put it all together and give it throttle it pulls the cable against the little slot that it sits in and pulls it out of the hole. it looks kinda like ( o- ) the cable goes thru the cirlce and slides to the right into the slot to hold it. but the way its made makes the cable pull slightly to the left so it comes out of the slot and falls thru the hole. does anyone have this carb? MAYBE IM NOT PUTTING IT TOGETHER RIGHT? PLEASE HELP!
