About this part

A pressure washer sits for months with fuel in it, and its carburetor pays for that every spring. This 591137 carb fits the 190cc 775EX to 875EXi engines used on 2700, 2800 and 3000 PSI washers from Troy-Bilt and others.

The mounting holes sit 46 mm apart on the throttle side and 35 mm on the choke side, a quick way to confirm the fit. It also fits the Toro TimeMaster 30-inch mower.
