This motor works great! It was on a pressure washer and the pump broke right after I just put new piston rings, crank case gasket and head gasket on, my luck. The model number to this motor is 12F4-E1 and the date code is . If you have questions about what this motor is compatible with, you will have to look it up yourself because I do not know. I still have the pump if you would like to have that as well for parts? X-posted. Thanks for looking!
