My pressure washer was surging and then would die. Cleaned the carb, changed the plug, still not working. Then this video says to check the breather on the gas cap. Brilliant!. Solved the problem. Thank you for the well done videos. Count me as a subscriber.

Gasoline starts to mix with condonsation and moisture overtime, is that why bad fuel creates residue build up

Thomas Guillot says:
