This thing is a power house for what I use it for half throttle is enough. I had the echo 8010 when it first came out and this Prorun is a whole lot better in my opinion. Absolutely love it I left one tube off for my height and works great. Easy startup after getting it started the first time after that it’s only a couple of pulls and it’s ready to go . Save your money and buy ProRun thanks for a great product
