Ok i just bought a new red max 7000 backpack blower, and its not getting to full speed. I don't know if the carb needs adjusting or if cause its new it needs to be broken in. Some times it will push out a little more volume then drop back down? I would take it back to the dealer bought I bought it when I was out of state, I saved a $100 but I guess it wasn't worth it. I adjusted the throtle cable, but that didn't help much. I believe there are 2 adjusting screws (1 for gas, 1 for air) on the carb and I think that if I adjust them I should be alright but where are they located?
