Review on Proform 66792 Dead Center Locater by Aaron Bannister

This small number helps to check the OT. It's about the size of a typical spark plug, so it should clean any exhaust manifolds or manifolds. As others have noted, the threads on the (inner) set screw are a bit sloppy, so I put a strip of teflon tape on it to give it a little slack to the touch. For $$ this thing couldn't be better. Revain received it in 2 days.
