I just got my Volcano up and running. Idles ok. When I try to go full throttle, it dies. I've tried to adjust the high speed needle but to no avail. If I go in with it, it wants to die. If I go out with it, it dies when I go full throttle. Any suggestions? I can get it to run. Only when I try to go full throttle it wants to die. I have to get on and off until it stops. Sometimes it does and sometimes it doesn't. Thanks.
