Works well. Easy to install.

Fit and did the job

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.

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.

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

I installed it on my motor and it didn't work. Gaskets are wrong for my motor and it leaks fuel. Made a copy of the original gasket and it still leaked fuel from the air intake.

exact match to existing carb

Cheap and worked great. The gaskets are way off and will take some cutting and trimming. If you can save the existing ones do it. However gaskets are minor and can easily be modified.
