Thanks for the tips guys. When I had the carb apart to clean it gas flows freely from the bowl out and the float doesn't appear to be hung up at all. I thought it could be the cap, the first time it happened I took the cap foam filter out and it helped some. I think for what a cap will cost I'll run to lowes in the morning and pickup a new cap. Of course this weekend it's supposed to hit low 50's and all the snow is going to melt, gotts love Michigan weather.
