I bought 4000psi 4gpm Briggs & Stratton about a month ago and have used my pressure washer 5-7 times for about 2 hours each. Yesterday I was finishing up a job and out of nowhere my engine just sorta slowed down while I was washing a house. I thought maybe restarting it would correct the problem but I had no luck.
The pressure is a lot less and the engine isn’t as loud as it was before. I checked the gas, oil for both engine and pump, made sure speed was all the way up and the problem persists.
I was wondering if any of you would have a hunch as to why my washer is acting up.
Could it be my pump? I thought it was the engine because it isn’t going as fast as when I first got it.
