Stored my karcher pressure washer over the winter and now it won't run. Will start if I spray carb cleaner in the carb intake but dies after a few seconds. Will continue to run as long as I continue to spray carb cleaner in the intake but dies as soon as I stop the priming. All this while water hose is connected but without wand and hose, just letting water spray continuously out the high pressure side of the pump. Looks like I need to drain the old fuel, check the fuel filter and probably take the carb off and clean the tubes like described in another post. Just want to make sure as I've already removed the carb and float bowl and sprayed carb cleaner in the jets but this did not solve the problem. Any advice?
