Well it idles much better now but the speed varies a bit and I still have some fuel feeding into the secondary Venturi. If idle adjusted low enough for the engine to be on the verge of dying the fuel no longer feeds into the Venturi. I wish someone with a “perfect” idling Zenith could take a video to see if any fuel fuel enters the Venturi.
So, it is much improved but it seems something else needs attention but I don’t know what is.
I’m questioning the float level spec in my manual since I had to adjust the float to a higher bowl level in order to meet the spec.
Do you good fellows have any more ideas?
