WOW! Look at the debate!!
And to think..... I wasn't even involved!
I have a question:
In your video.... you don't have an air filter or muffler on. Neither of which would be required to remove to repair or replace anything you mentioned. (Aside from cleaning the carb..... you have to take the filter housing off for that.) So.... when you were mowing with it, was the muffler and air cleaner on it? Why is the muffler off anyway?
