hey guys, i just recently replaced my gray fuel lines with automotive fuel lines after it was surging at full throttle and cleaned the carbs as well. I took the ski out today for the first time after replacing the fuels lines and cleaning the carbs and the problem has gotten worse! the ski maxed out and ran good for about a couple minutes than began to surge and get slower and surge more often. i replaced my new plugs with my old ones and it ran good for a minute than began to do the same thing. than i put my new plugs back in and it ran better for a little bit longer but again started surging to the point where i thought it was going to stall. ALL HELP IS APPRECIATED!
