first time at buying a carburetor for a small engine, usually I just clean them or buy a carburetor kit and rebuild but not any more, I couldn't get the carburetor that I had set right and it would leak gas because of the float not being set right so after taking it on and off 5 times to adjust the problem I decided to look at the price of a new one and boy was I surprised because I picked this one up for less then a kit and my time and being skeptical I figured it would not fit or I would have to adjust the settings but I put it on and pulled the rope and it started and ran better then the old original carburetor and I didn't have to touch a thing it was already set.The only thing that took me time was finding the right carburetor, the unit I have is old and not listed so I had to look at a lot of pictures before I found the one I thought would work and glad I did because after this I don't think I will ever rebuild one again.
