Rigid Pressure Washer Idle Problems

I have a 3 year old Rigid 3000psi 4 stroke pressure washer that has about 50 hours of use on it. I've used Stabil in it each winter and it has never sat idle for more than 3 months (always with Stabil in it). The past few times I've used it it starts a bit hard and while idling the RPM's audibly cycle high and low to the point where it will die. Any ideas about what may be going on would be greatly appreciated as I'm a novice when it comes to small engines.
Thanks

I'm thinking the carb needs to be taken apart & soaked in a cleaner & a repair kit installed (I know you use stabiliser, but todays fuel is junk???) Let us know what you have for an engine & we'll dial you in for part #'s.. Roger

Thanks. It has a Subaru SP170 Engine, part number 309590001. The pressure washer itself is a Ridgid RD80746. I appreciate the help. Sounds like it'll be a fun weekend project.

Problem Solved

Thanks for suggesting the carburetor as the source of the problem. I took it apart, cleaned it out, and found that a thin veneer had build up on the main jet. I stripped down a twist tie to get a thin enough wire to push it through and break off the veneer, and I cleaned it well with a standard carburetor cleaner. Now it runs like new. Thank goodness for this forum and helpful videos on youtube.
