I have an Echo HC-1500 that worked fine when I was a flatlander but now that I live in Reno at 5000 feet, doesn't run worth a crap. I tore the thing apart ,checked everything, played with the jets, and googled.
I checked with my neighbor, a commercial landscaper, and it seems in the business these are known as "green machines", they avoid them like the plague. They are designed to run lean but at this altitude, I can only open the throttle %25 before it bogs and dies. One trick they use is to partially choke them, but it doesn't work on mine.
The jets have plastics heads which allow only a fraction of a turn, and I can find no info on the net, including the Echo website. I thought I was buying a quality piece of equipment but didn't know I was getting into this crap.
Does anyone know how I can get this thing to run right without spending another fortune on it?
