Re: Ridgid 3300 pressure washer throttle problem
I think Ive figured out the surging, backfiring, and eventual shutting off issues with the 3300 EFI unit.
Ridgid techs, repair shops offered no advice other than use "ethanol free gas". Mine ran like crap for a year and a half until yesterday when I decided to adjust the two screws behind the EFI unit. There are only two a big one and a little one that requires a very small phillips driver. Backing out the large adjuster a few turns and screwing in the small adjuster a few turns got mine running perfect. After i got is running pretty good with this method, I fiddled with it until it was really fine tuned. After I did this the damn thing ran perfect all day with ZERO incidents. that was the first time that has ever happened with this unit.
