one carburator appears to be puting out twice as much fuel as the other.
Are the carbs a matched set? I ran into that issue when I was running Carter YFs. Both carbs were Tomco re-mans, supposedly the same application carb, too (part # on the boxes were the same). But internally, they were very different. Turned out that the first carb was a correct 235 application, but the second carb was for a 300 Ford, which runs about double the jet size. I ended up gettin a pair of $20 apiece junkyard Holleys, rebuilt and rejetted them myself, and haven't had any trouble since.
