I just did mine today and used a steering wheel puller and some nylon wire ties. I used the wire ties to loop around the trigger wheel and then loop to the puller body. It worked like a champ!
I was having too much mechanical advance and wanted to see if everything was still in place below the plate. Just my luck everything looked O.K., but I noticed where I was supposed to have a heavy spring, I had a medium one. I have looked every where and cant find one. I know TEAMRUSH posted that he had some but where did he get them?
I am thinking of just shortening the spring and seeing what that does.
