I'm not sure the delay relay is the issue - in that the system is still operating under these conditions, rather than cutting out. It is more the fact the plate is vibrating so rapidly - you can just see it as a blur. The relay delay would not stop that, and clearly this should not be happening. My SC does not behave like that. There is a damper system in the fuel head to prevent that altho what you do to recify it, I am at a loss. I could pull the fuel head apart, but what I'm looking for I would hardly know - the manuals really don't go that far. I am mystified as to what would set this oscillation up. I don't know what cams are in it, but overlap would be more an issue at high revs I would have thought - altho lumpy cams do produce poor vacuum issues at low revs. But then, when I steady the plate, it stays steady. So, I suspect the damping in the fuel head.
