Finaly got the olgirl running and run pretty well i have adjusted the carb as the book says still turns the muffler red but think im gonna try and get a new carb it still lacks power some i know its only a 12hp but just feels like its holding back some but thanks for all the help and butting heads with me some . Gonna take the mower deck off soon and put on a snow plow and see how the olgirl does when its performing at its best when i get a new carb

Carbs don't "go bad".
