I recently have worn out at cat pump to where its not worth repairing. it has about 1200 hours on it . it was a lower end 4.0gpm 4000 psi that paired with a honda gx390 . i was thinking of getting the same pump or maybe the general pump with similar specs . the cat pump as the built in unloader but i use a k7 unloader off that anyway. I also might sell it and get a new machine but haven’t decided on what yet .
Time to upgrade to a v-twin man.
for now its getting fixed lol
