I have a 1988 dt85 suzuki 3cly ans it runs very erratic, It will start fine and run at WOT 5000rpms for 7-10 min,then all of the sudden it will die down but will not stall and run at 2000-2500rpm at WOT. I will turn the boat of let it sit for aprox 2-5 min then it will run great agian for 7-10 min. I have rebuilt the carbs, new spark plugs new fuel tank, fuel line, fuel line connections, thermostat, fuel filter, oil filter and the compression is aprox 130 all round. water comes out of the pee hole fine. I need some help please. :)
