I'm going to attempt to rebuild the carb. I'll start by using the 37-1543 kit, but understand I may need to order some other parts from Holley. Since I'm not in a hurry, I will order as I need things. I opened the kit, and first thing I notice is there are two gaskets for the carb base. The thicker fiber one has holes that are too large. My research has led me to believe that is for the larger cfm carb. Mine is a smaller cfm, but I'm not sure which. 428083-C91 LIST 6394 So here is a picture of the base of the carb, and the smaller of the two gaskets. Does this gasket look like it is correct for this carb? I'm not convinced I have the correct rebuild kit yet.
