Motor runs 5500 rpm for about 5 mins. or so just fine, then starts cutting out and drops back to 4000 or 4500 rpms. If I let it run slow for a little bit it will go right back up for a few minutes. It has had carbs checked new fuel lines, and fuel system flushed. I mix the oil my self. The oil lines have been disconnected. The over heat alarm goes off but it is not over heating. Any help would be greatly appreciated,Bill
