Upon opening the box, the air cleaner was a jar, it would not snap into place because the motor location is too far to the side because of the welded motor mounts. I had to cut an inch out of the top of the air cleaner housing to make it Fit and hold the element securely in place. With my first use, it was awesome until I stopped and realized that there was gas draining out of the carburetor because the bowl drain plug had vibrated loose and fell out, luckily I was able to retrace my path and find it . So far two weeks in and it is performing flawlessly.
