Anyone own a Ford 3000? Had the 8N for a long time and last fall purchased a 74 3000. Great tractor with lots of power and handles great. It has a Zenith carb. I just noticed though it seems to use a lot of gas. I looked up on the web and the 3000 should use between 2-3 gallons of fuel an hour depending on your usage. I just filled it up and it took almost 10 gallons. I mowed a little last fall and have plowed snow this winter with it. I'm pretty sure the 8N didn't use that much fuel. Maybe I'm wrong. This Zenith carb doesn't appear to have any adjustment on it. I'm betting it does but I do not know how. Can't find any info on that carb either.
