Engine sputtering at about 65

Dave Haertel said

This was hard to test because the idle is set higher than 500, but it did seem a little weak so I’m replacing the fuel pump this morning. Luckily it’s fairly easy to get to. Will report back what I find.

Oh jeeprs, that's the minimum, there is nothing to stop you from testing at a higher rpm,lol. I guess I should said that. I'm not big on throwing parts at a problem. But if it's a Holley,I would check the manifold vacuum, at the point of the problem, and throw a new PV in it...........of course I have a tester for that............
For me, the testing is the fun part.
