    kohler K301 rebuild kit

    Posted by on Oct 21st 2019

    This is a very complete rebuild kit. Everything fit correctly and worked great. I didn't want the carburetor, but i am glad i have it. The old one had a lot of wear in the throttle shaft and this affected idle. The new carburettor works great and idles nicely. The price was very competitive.

    Still in box

    I haven't gotten around to rebuilding my engine yet so I can't really say how well this kit works. It looks to be complete and of very good quality though. The box it was shipped in suffered some damage at some point in the journey to my door bUT it doesn't look as though anything in it was hurt.

    Comes with almost everything you need, depending on the depth of your rebuild. Valve guides are sold separate but at a great price.

    I was blown away. The parts and pieces are all very well machined and/or manufactured. The packaging was tight and professional and the internal wrapping complete. This is definitely NOT one of those "cheap online no-name" kits.
