I have a Redmax EB7000 that starts up and runs just great. After running at full throttle for a while (like 10 minutes), it'll start to lose power and die. It takes about 5 seconds from when it starts losing power to stopping. Once stopped, if I immediately pull the cord, it'll start right up again and continue to run for a few minutes until the cycle repeats itself. Also, it seems to run really warm, since when it's good and warm, the stop button won't do much. I have to hold it in for several seconds to get the blower to stop. When cold, it stops immediately. The spark arrestor has been removed. Running 87 octane and valvoline 2-stroke oil. Just as a test I mixed one tank with too much oil, and it still died. Any help would be appreciated. Thanks!
