I just checked the Dynojet web site and they are calling for shims ABOVE the clip. That doesn't seem right. I only have one under the clip now, but this gives the needle quite a bit of upwards movement (play). See page 2 of this link http://www.dynojet.com/pdf/2157.pdf How do I tell if I have Dynojets?. The main is a 108 so I think it maybe it is. Confused...
