Richard Jackson –
I never realized how crappy my old carb was. Even after I rebuilt it, I kept dealing with the hard starts and rough idle. Well no more the mower fires on the first bump and idles so smooth now. It runs like it is new again. I was skeptical of the quality because of the price, but I will never rebuilt a mower carb again. I should have just bought this two years ago.

Used on a Toro Wheel Horse Model #71227 Serial #240004248.The other cheap HOOAI 594593 carburetor that I tried first (with the mixture screw) was backfiring and ran terrible.Updated 10/12/2019Carb failed. Gas in my oil.

Wasn’t exactly how it was describbed! The motor surges no matter what we did to try to get it adjusted out!
Allison Shew –
Great kit
benoit –
Tres bon rendement…Demande un peu d adaptation, couper le surplus de plastic sur la clanche du choke.

Installed on my 17.5HP briggs and stratton, worked great and included all hardware needed.
Ronnie S. –
Just what I need to get that old tractor back cutting lawns.
Julie –
Everything fits as it should, and idles great. As soon as you put it under load it is starved for fuel. I also adjusted the amount of fuel. Got an OEM briggs carb on it and it runs great.
