Rebuilding carbs, 1995 CB750 Nighthawk. I have 2 manuals. In the carb breakdown the jet I am concerned with says it is a Slow Jet the other a Pilot Jet. It's the short one that is offset from the center of needle. My issue is that there was a lot of corrosion on all the interior carb parts. Is this jet supposed to have a hole all the way through from the bowl end to the end with the small holes along the tube? It appears there is no hole all the way through, and I am afraid to use my micro tools to drill it through. This is not in the parts kit I ordered. Can someone tell me that there is no hole all the way through and if yes can I clean out any corrosion that may be blocking it?
