"1998 25HP 2STROKE YAMAHA. STARTS AND RUNS WELL AT LOW AND MID RANGE RPMS IN GEAR. IT WON&#39;T OPEN UP TO FULL THROTTLE. DOES NOT BOG DOWN. WHEN CHOKED IT WANTS TO SPEED UP FOR A MOMENT. WHEN CHOKE PUSHED BACK IN, AGAIN IT WANTS TO SPEED UP FOR A MOMENT. THINKING BLOWING OUT AND CLEANING CARB. ANY SUGGESTIONS OR IDEAS ?<font color=""0000ff""><font face=""arial&#44;helvetica""></font></font>}"
