Unpacked a new gio 50 today and run into a problem. After changing oil and starting it, it only runs with the choke on. If you take the choke off, it idles too slowly to run more than a few seconds. It quits even if you "feather" the throttle with the choke off, but seems to run fine (although fast) with the choke on.
Does this sound like a problem with the gel pack? Does the idle screw on the carb need some adjusting?
Any other ideas?

Thanks.
