I keep reading along and thinking there is an issue with the sprocket. In forward, the first two bushings contacting the sprocket teeth have the force. The rest just ride along lightly. In reverse, all of the bushings in contact with the teeth are sharing the load. If that isn't correct where they meet, the bushings will ride up the teeth and pull the top of the chain towards the rear. That will pull on the idler and force it rearward against the spring.....

Bill....regards posting pics.....first of all...do you know how to put your pics in the computer...? like when you want to send some pics in the email?.. if you can do that we can certainly help you get the pics posted to this site. Several ways to do it...do you use camera or phone to take pics.?...

2nd....have you registered for the jccrawlers pic server site?..if you have it will be very simple to help you get them in. If you have not registered to that site yet...send message to Lavoy he will need your login and password to set up....either send using private message board here or email directly to him., once you are registered we can help get them in.
