I’ve been having trouble starting it and figured it was the battery since its bad, but once I charged it up and got it going it wants to die when it idles lower. When I was going to park I looked behind me and saw a cloud of white smoke so I shut it off right away. There is some oil in the back of th carb and some on the big black tube thing that attaches to the carb.. tht must b bad.. blown head gasket or worn rings?
