Last one I timed like that, I used 175 chart. Close enough for me. Others will disagree, but after I pinned the pump with the dial indicator in it. That was the closest chart.
 
That pump have funky delivery valves in it? Constant pressure I think they're called.

Not taking anything away from Colton's real world results, just saying, the "book answer" for cpl 1262 is 11* which is 6.35mm lift.

So is it pinned @ 11 degrees of timing? Its definitely 11mm plungers?
 
Just for future reference if anyone was wondering; The 6 and 7th digits are the plunger size, right after the "P", which indicates that it is a P-pump. And the 7 after the RS at the end of the numbers indicate that it is a 7000 series pump. This is how I've understood it.

Thanks.
And thank you to everyone else.
 
Needs some more help.
Started to install some 191 delivery valves but when I pulled out the existing valves they looked very different.
Im guessing my 191s won't work? If not do I have any other options?
191 valve on the left.
