I have a buddy who has a 97-10, he said it was running slow.He disconnected the motor ,took off the cover and took out the part to clean. I guess they are some kind of points or brushes,i have not seen the motor myself.Well he put it back together ,said it started strong,runs good ,but it runs in reverse.He said he changed the wire connections,but still runs in reverse ,any ideas would be helpfull before i go visit him.Thank you for your time.
