Yep - just installed one so that I could get a solid metric on what the fuel pressure was at. Looks to be at 3.5lbs at idle after just starting it up.

Good call on the cam lobe wear. I have no idea how many miles are on this 225.
So my question is ... is 3.5lbs of pressure enough? I notice when I punch the throttle the pressure doesn't change (not sure if it should though)
If I was to install an electric inline pump like
this one before my gauge, maybe that would be a quick low-budget test for the fuel pressure issue?
