I have a 2300PSI Generac Pressure Washer powered by a 6 HP Tecumseh. The
water coming out doesn't have much more pressure then a garden hose. I
thought it was due to a dirty nozzle so I used the nozzle cleaner kit
but that did not improve the pressure.

I'm wondering if there could be a problem with the spray gun or are
there other places I should look for an obstruction?
