Most the time I've come to this,. It's the spring not putting the kicker in the correct home position. I know that much,. But when fixing it, I'm not sure, cause I never had to. A solution tho,. You said the kicker wasn't even on the motor,. Look up and see how tough it'd be to go inside and remove the spring or cut the kick shaft in half so it doesn't contact but also doesn't lose seal for your oil. First though,. I'd get some channel locks or vice grips,. And hrab that shaft and try to turn it backwards while it's running and see if that stops it. If I remember right,. The traxs kicked forward,. So you'll turn it back and try to return it to home position.. never know,. May just have just build up holding it off a tad . Good luck
