The title pretty much says it all, i just got done installing the motordyne 5/16 spacer and i followed all the directions to the tee, for some reason when i went to start my car i reved it and noticed the RPMs didnt move at all. is there somthing i could have missed? Any help at all would be greatly appreciated.

 

New one on me. Can't imagine what is causing that other than knocking a connection loose, and I have no idea where the tach connector even is.
