My 9.9 gamefisher motor runs great at idle to mid range then it acts like it's either getting too much air or too much fuel, my fuel mixture is probably around 43:1 mayb 48:1 so I don't think that's the problem, I'm not sure how to really gain access to the carb and fuel lines to make sure they are clear, I did however get a camera to where I can see the butterfly valve and it appears to work fine, any ideas would be great. Also how do I take the lower engine cover off? Do I need to actually take the engine out? Thanks for the help
