I have a 83 25hp sn-6129796. Been sitting for a month, prior to that was very hard to start on the water (10+ pulls) I just added elect start. I am unable to start unless I put in gear 1/2 throttle and pull. It will run in gear at 1/2 throttle then when I put in net. it dies, and the plugs are soaked. The # on the carb BC110 8489, the # on the fuel pump 1364-4929 If I rebuild the carb where can I find a rebuild kit or the gaskets?? Any help with this would be appriciated.
