Looked identical to OEM carb. but it came with gaskets that wouldn't work for me. ended up returning carb and have a small engine shop clean carb and they had the correct gasket.

Our old EX21-powered go-kart didn't idle well or make much power; we were thinking it was time for a Predator upgrade.It recently stopped running off-choke, but the kart doesn't get a lot of use so I was reluctant to splash out for a engine and torque-converter swap.A friend said he was really happy with an Amazon carb he'd put on an old WheelHorse, and at less than $20, this generic carb was a low risk option.My 16yo installed it.It started on the second pull.It makes at least 30% more power than the OE carb (which to be fair is years old and hasn't been maintained). Not exaggerating, seriously.Even if it only lasts a year, it will be money well spent. It's *already* money well spent.

Replaced the carb on my Rigid pressure washer and fired on first pull! Buy this and quit looking elsewhere!

This carb fit straight out of the box, came with new gaskets and was 1/10th the cost of the original Mikuni. Now have over 15 hours on the washer and working and starting like new.

Works well. Easy to install.

Fit and did the job

Installed after having it sit on the shelf for about 5 months in its original packaging. My pressure washer starts every time with it but then immediately dies. Unfortunately the carb does not seem functional and I am out of the return window.

Engine runs great after the carb swap. No hiccups or surging anywhere in the range. Had to give it 3 stars because the gaskets are absolute trash. Not one of the three lined up correctly and I tried every possible orientation. I had to use the old gaskets as templates and cut out my own.
