Landa with cat pump question

Hi all, thanks for having me here. After work today I’m going to take a look at an older landa pressure washer with a wisconsin robin motor (model m1-390) with what I believe is a Cat 310 pump. He says the motor works great but that it doesn’t pump…he’s only asking $75 dollars. Should I go for it or hold off?

Hmm. I wonder how old it is? If it’s relatively new I might risk but if it’s older I would pass unless you have some other use for the motor. Honda’s are the gold standard. If you’re going to gamble I would probably only do it on a Honda. Also is the motor 13hp or higher?

It seems to be an 11hp motor, but older…for 75 bucks it seems like if I could rebuild the pump and come out ahead.
