Re: Generac pressure washer runs high rpm
Well I got the used pressure water motor running again. Turns out the throttle plate had been installed backwards. I reversed it to see if it would "seat" better, and it did. So I tried it, and it settled in to a more normal rpm range. It is running now at 3500 rpm, which may be a bit high, so I will probably drop it a bit by adjusting the governor linkages and/or spring. I'll add some more gas, and run some Seafoam through it just to clean out any old deposits. Then I can drop the rpms a bit, and put away till spring. In the meantime, I'll look for a replacement water pump.
Thanks all for the suggestions. Note that the Briggs part diagram for this carb did show the throttle plate in the incorrect position (180 deg out). It's not really an assembly diagram, but the way the part is shown is apparently not how it ends up assembled, so I can't really fault someone else for having it this way.
Every time I think I know a bit more about small engines, I find out how much less I really do know. Thanks again.
