Someone has already changed the carburetor on this unit. Originally it had a 698558 carburetor and it now has a 796447. This is basis on the datecode which is 2 years before the 2009 introduction of the 796447 carburetor.
This carburetor has a separate main jet and it no longer uses the fuel nut as the main jet. This might be situation that requires resizing the main jet but exhaust all other possibilities first.
For carburetors here I use an ultrasonic cleaner which seems to penetrate better than just the soaks and doesn't damage rubber parts since it use only soap and water.
