Check the throttle cable for binding.
Check intake clamps not interfering with the carb linkage.
Are the carbs in the boots the whole way? -
the throttle cable and linkage moves freely. the carbs are in the boots all the way and the boots appeared to be in good shape no serious cracks or anything that i can see.Comment
