I picked up a new carb kit for my CL175 and noticed that the air adjustment screws were different. The original ones had a hole drilled below the threaded section both vertically and horizontally while the ones in the carb kit didn't have anything and the air screws were solid. The carb kit was a keysters. One thing though. I looked on ebay and found some NOS air screws for CL175's and they didn't have holes even though their oem honda screws. Here's the ebay NOS honda ones. I may be blowing it out of proportion but thought it was odd. Does it matter?
