After Seafoam, and a half-hour of idling:
There's a detectable difference there, I think, although holy crap that fan is loud. Still a little rough, I'm hoping new plugs and wires will cure that. If not, I'll have to start checking for vacuum leaks or fuel/air trouble. I need to change the fuel filter, and I probably ought to lash the valves, too. That'll be a first for me, I've never done that before. One concern is the oil pressure - it's very low at idle, but creeps up well past halfway when I race the motor. I don't think the 22RE in my '86 did that, should I be concerned with this? Or is this normal and my old motor was the weird one?
Look what I found in the airbox.
It's completely filthy, so I ordered up a cleaning/recharge kit for it. Should I run it through the dishwasher first, or would that hurt it?
