I have a 2600psi gas pressure washer with Kohler Courage XT-7 (173cc) engine. Been running fine but lately when it warms up and you hold the trigger down for a while (10+ seconds) it will begin backfiring out the intake and fall flat on its face dead. Completely repeatable, does it every time.
I yanked the carb off cleaned it real good, no dice. Replaced with new cheap carb off Ebay, still does it. Tried removing fuel cap, no luck. Replaced fuel line. I adjusted the valve clearance, no concerns there, valves move freely as they should. I'm really beating my head against the wall with this thing, nearly to the point where I'm ready to toss it and get something better. This is a cheapie unit with vertical shaft engine and junk throwaway pump, but it has served me quite well since around 2008 when I bought it. It was a $179 Black Friday special at Menards. Figured the pump would fail long before the engine, but it's treated me good and instead the engine is giving me fits.
Anything else I can check on this unit? If not, I'm open to hearing recommendations for a new pressure washer in the $400 range, I'm hoping to get something that I can replace the oil in the pump (in other words, not a cheap throwaway pump), I really have no preference as to engine, but might try avoiding Kohler due to the last pressure washer experience.
