Hello so I have a 1978 15hp that won't idle right. I bought it like this. It starts right up and runs good and even "idles" with the throttle advanced to start location. Once you twist the throttle down past start she dies. I have the "idle speed" stopper knob dialed in as fast as it will go but never even make contact with the stopper before it dies.have rebuilt the carb. Upon rebuilding the carb I found the slow speed needle to be slightly bent so I figured this was the issue. I replaced it with new part and still no idle? I have the slow speed needle backed out 2 turns from seated. Please help I'm at least $500 into this motor so im hoping to get it running right. Thanks ahead of time
