[Craftsman 2500psi power washer]

excuse my ignorance, so the throttle plate sits atop the carb where the throttle cable attaches.

[Craftsman 2500psi power washer]

10+ year old craftsman 2500 power washer.  Shuts down after a few minutes under load.  Decided to give it a once over; new carb, new air filter, new spark plug.  Added new pump oil.

Remove/cleaned unloader valve.  RMP is now low, and wants to shut off.  RPMs were fine before.  Thought possible bad gas. Drained/cleaned gas tank, removed and cleaned carb.  Still

low RPMs.  Any help appreciated.
