I have an '88 Johnson 200hp looper. I ordered carb rebuild kits and this weekend I went thru the carbs using my kits and the OEM manual. While the manual and the kits were for a similar carb, it was obvious mine weren't identical. The main difference was the manual called for a low-speed air bleed orifice, and my carbs had a needle valve for the low speed circuit. Any ideas how much newer/older the carbs are than '88?
