Probably why most run 40-1 now, yep it was probably direct drive problem was when it eventually warmed up it still had a terrible bog on the top end of the power band until I opened up the H speed adjustment screw, however low speed and idle never could get it acceptable to where I could use it. still a complete POS and I expected more even at the price I paid. I owned and used two cheap boxstore weed wackers for a decade previously at my cabin and made them work for occasional use. I can say the echo 225 I eventually bought is a completely different level of qaulity for less than a hundred bucks more and completely worth it in my opinion. And still about a hundred less than a Husqvarna I use at home and was looking at for up north.
