That is like the VariCam minus the spring. Dad ran one for a long time before he switched to Rhoads lifters. Mr. Rhoads invented both, we were told.

OK, I see the the adjustment mechanism now. But I dont know what that eccentric is for or that hair spring? Now we got oil pressure activate VVT tech. I think Triumph had a vacuum operated VVT that was sun gear (planetary gear, brain fart) operated?
