These are the numbers. I think your right while I was waiting for your replay I tried a spray carb cleaner just for something to do and it did help to a point but not much.
Is this a repair I can do or is this a shop job. The guy I use is almost as expensive as replacement with new stuff. I have a small yard so this is a pain.
See attached link and go to page 4. The problem is most likely the diaphragm in the carb. It is a pretty easy repair.
I do not get paid until you hit the green accept button. Are you located in PA?
