earlier i went to start my 36'' and it took awhile to start. once it dies it was pouring out white/black smoke, more white though and kept dieing. I finally got it to stay running, but it still smokes. I did notice the the rubber hose between the carb and valve cover is ripped up pretty good. What could be cause this? Note, earlier that morning i did notice the carb was dripping alot of fuel, but doesnt now. i hasnt given me any problems before.
