Can anyone give me step by step instructions on how to replace the seat and needle valve on my 1987 50 hp Force engine? It started dumping fuel and I was told to get the repair kit. I tried replacing it yesterday, but still the carb is dumping fuel. The kit came with more parts than I recognize and two separate bags with the needle, cork and retaining clip. One bag has an extra spring that I don't see on my carb when I took it off. Maybe that is the problem?? Pictures would be very helpful.
