This is a good kit, fairly easy to install. I installed this kit on a Harbor Freight Predator 212 engine.I had to acquire (4) 5/16-24 x 1 bolts for the install as these are not in the kit. I also found that the spacer for the drive unit was too short as the belt was not in alignment, probably causing belt problems noted by other users. Fortunately I had some 3/4 x 1-1/4 DOM tubing and was able to finish to proper length, I am sure you could use washers to achieve the same results.
