Right, it works. I pulled my new (changed prior to departing on my present
extended trip) irridum sparkplugs as I was messing with the idle.... I, too
had some concerns about running lean, but the plugs read "perfect". It's
very easy to access the plugs, oil cooler, distributor, water pump in the
50 degree diesel/style inline gas installation.
I choose to think the throttle stop maybe actually needed adjusting
after 30 yrs of stopping the throttle plate.
