Rocker Arms Strange One
I have 2 rocker arms a PRW and Elgin stainless type the Prw get very close to the edge at full lift and the Elgin style roll dead center with good geometry
anyone else see this I bought the PRW years back from Ace Brewer. I may try running the stainless style any bad news with them? |

Actually this rocker in the first photo looks to be centered better to me, but that’s at max lift.
Any way the contact should be centered the best at half of max lift, not at max lift. PRW parts where known to be at the low end of the quality scale!

Sorry, I should have noticed that the valve was closed!
Are they both the same ratio? Even if they are I bet that if you check the total lift with both that one is .maybe 020” different then the other!?
