Doesn't appear to but I'll have to double check it. Would that affect the operation at high throttle though? I agree it's not getting enough fuel but is it a vacuum problem in the tank? I don't think it has a vented fuel cap so may try to pull the tank vent and clean it and see if that helps any.
Not real likely. Could be the carb needle is set to low ? Or sucking air into a line some where ?
