I'm researching, trying to find what I believe to be the best backpack blower on the market today. First of all, I'm only interested in a 2-stroke engine. So please don't recommend the BR600 or EBZ8520. I'm very aware they're good blowers, but that's not what I'm looking for. I believe I've narrowed it down to three models. Shindaiwa EB802 This unit is in it's 3rd year of production and is a bullet proof model. It's performance is near the top of the pack. Even then, it's said to be undertuned from the factory with an easily modded muffler, that gets it closer to it's advertised maximum power. I've seen that an adjustable carb is available, but have not confirmed that or found a PN for it. Redmax EBZ8050 The EBZ8001 has been reguarded by many to be the best blower. Many say that the 8050 is not as strong. However, comparing the IPLs shows every part in the engine, exhaust, carb, ignition, blower housing, and impeller to all be the same. Someone mentioned that the 8001 had an easily modded muffler that the 8050 does not. I'm still trying to sort through this. If it's simply a few mods to make it what the 8001 was, then I have no problem with that. Echo PB-770 Said by many to be the strongest blower on the market, but also said by some to have exaggerated specs, and be no stronger than the competition. It's also a newer, less proven model.
