502 Mag Mpi throttle body question???

I recently had my throttle controls and 3300C cables replaced, and today i had the flame arrestor off to clean it and noticed that when I put the throttle all the way forward, the second throttle body port blade only opens about 3/4 of the way? I never looked at it before I had the cables and throttle replaced, but that doesn't seem normal, is it?

Unhook the cable and see if it opens fully with no cable.

+1 then adjust with the stick at idle. Make sure it comes back to closed before starting. I like a little pull towards idle. Artie

It opens all the way when I unhook and open with my hand.

I just checked mine, the blade towards the transom opens 1st about 1/4 way then the second blades starts to open. At WFO on the stick both blades are fullyy open ( 90 degrees).
