Good story. If anyone gets one, make sure your fire extinguisher is an "ABC" type. I keep one nearby, not on my cart, but I have one in the garage, shop, and on my truck.
On the carb, that's great! Don't you love it when a $20 part solves a problem? Hopefully it will stay that way. Usually those chinese carbs are junk out of the box. Some people have reported good results though, we'll add you to the list.
