I have a 1983 Johnson 175 that appears to need the carbs rebuilt. I was about to order the Sierra kits form here but have read that they have been problems in the needle and seat areas as well as gaskets. Some have mentioned to use the OEM kits but haven't said where to buy them. The marine repair guys around here don't seem to want to sell me the kit but rather pay them for something I can do. So..... my question is where to find the OEM carb rebuild kits or are the Sierra kits from here sufficient. I DON'T want to use cheaper parts that may cause more trouble.
