Good parts but wrong description.
Got all that was described and shipped fast but the description says "EGR Head" and it is not. Had the description been right I would have ordered a valve cover too but since the description said it was EGR I figured I didn't need to. So we will see if the seller makes it right. I now have a fully rebuilt top end but no vale cover to put on so I miss out on the family fun for the fourth.

Absolute junk
This was absolute junk the cylinder wouldn't go in the engine because it was to big I ordered it for the 57qmj engine which is on my engine and the piston was to big and the rings were thinner I would return it but I got so mad I broke the thing, I'm never buying from these people again all the positive reviews must be made by them.

Affordable
Liked the fact the set came with everything needed. Might not be the highest quality items, but sturdy enough for a small engine. Easy to put together, all parts fit well, no modification needed.

Great kit
Just installed this on a trail master 150 XRS.Everything fit perfect. It would be nice if there were instructions but you can easily find a video on YouTube. Engine fired right up, hopefully it lasts

Cam/piston is too large for the cylinder. Snap rings for piston are too small for the cylinder. Very unhappy
