midniteauto

I have a 1993 fzr600 I ran out of gas 3000 miles ago then I put it away for the winter and would periodicly start it to make sur it still ran. It has latley not wanted to start. I can spray starting fluid in the carbs and it will start and continue to run but if it sits for a day or 2 it will not start again until I spray it. Any advice??
