Alan, which jets have the larger holes?? The new ones, or the ones that were in your carb? Someone before you, may have enlarged the holes in your jets with a drill, which is a big no no.
Do the new jets have a “D” or “C” stamped next to the number? It doesn’t look that way to me, but the two different letters indicate opposite fuel flow directions. Keep in mind that the fuel inlets may be tapered slightly which is normal…But, your pictures sure make it seem like the actual hole diameter is different on the two jets…
