I've had this 77 400 AW since it was new. Done a couple overbores and crank seals.
Problem: Lately been running progressively worse ....needs more throttle just to keep running ( won't run below half).
Not a compression problem or crank seals.
My suspicion...could wear on the throttle slide cause this? The throttle slide is kinda loose.
