Making a good one from two: Karcher B202 and K2 14, frost damage and motor failure, full repair.

I think the reason why its pulsing is that its not able to build pressure in the pump chamber.

It's amazing! I really repair anything 👍 It seems that there is some air in the pumping a little, but there is no problem if you use it at home!
