well, I cant beleive it started first off... I have a Karacher 2400psi with a 5hp honda motor(yup happened to be honda.) It was given to me by my dad when he got a new one 4 years ago. Its been sittin in my backyard for the past 3 years n I decided id try n fix it. Turns out it started right up.

I changed the oil, filled with gas(was empty,) n changed the spark plug. Engine runs n starts great but the pump is givin me problems. When im usin it it works perfectly until i stop shooting, when I go to shoot again it has no pressure and I can hear the pump isnt workin. I take the tip off and let the water shoot out(large volume) then put the tip back on and it will work fine till i let go of the trigger again.

Do I need a new pump? or is it something else?

 

nm, after askin my friend at work(home depot tool rental) he said it was a stuck unloader valve. I googled it and found directions on how to fix it, all i needed was some white lithium grease n it works.

 

There you go..as I always have said..google it
