Well, it's starting to get warm again. How do I know? Is it the birds singing? Is it the buds just starting to crack open with new flowers? Maybe it's because we're mowing most yards now almost every week. NO! I know warm spring weather is here because my RedMax 8000 and 8001 blowers are starting to bog down at various times of the day. Man, this is getting really old but I have done some studying and researching on this and have created a temporary solution out in the field. I've tried everything to fugure out what is causing this and have come to the solution it's a "too lean" problem. I suspect RedMax's solution to reduced emissions is an extremely lean mixture and sometimes it gets a little too lean. I suspected this when one day it was bogging so I pulled the air filter. This made the problem twice as bad so obviously, that solution was heading in the wrong direction. I had even heard of other guys here on LS who had their dealer increase the size of the jet in the carb just slighly. Larger jet means more fuel. So what's my temporary fix? It's actually quite simple when this frustration hits. Set the blower on the ground and open the throttle all the way while running. It obviously should be running like a sick dog. Now start opening the choke slightly and you'll hear the rpm's start to increase. Keep increasing the choke until it starts going back down as if starting to flood. Now back off the choke a little to get it back into the "good range" and you should be good to go. Remember, the choke closes off air flow. I would guess this solution makes your 8000 run like a 7000 but it still beats it running like a 1000.
