I posted this a few weeks ago, and none of the suggestions seem to be helping. So here is a video that I thought may explain what is happening better.
When I sqeeze the accelerator trigger, this knob clicks and flips to the far left (as it is supposed to) and then it slowly dies. It slowly started bogging down over about a 2 hour period until it is now doing this. But if I manually turn this knob (as shown in the video) it will rev up to what is almost full speed - but if I click to full choke it backs off. Tried to show this in the video.
It is a fairly new blower (I year old - light farm use - 2-3 times a month for an hour). I use only ethanol free gas, and put a new fuel and air filter in which didn't help. Also tried spraying in some carb cleaner.
Any advice would be appreciated.
