I have owned this for 20 years and it has been maintained meticulously even though I only used it maybe a dozen times. Every spring I relube the pump, refill the gas tank and run it even if I don’t use it. I recently replaced the air filter,NGK spark plug and oil change. It has a newer pressure hose rated at 3200 psi. I am unable to use it anymore due to my disability so I have offered it for sale. Cash only, price is firm.
