The engine is on its third season now with no problems whatsoever. This has been one of SEW's must successful conversion kits. The parts that came with the engine including the brackets, wiring, PTO parts, muffler, and heat shield were all of the highest quality. This engine is the best running and performing small engine I have owned thus far, it's very impressive.
With that said for SEW's 682/782 conversion, some of their kits for other tractors do look like hack jobs, requiring you to cut holes in the side covers or use a diffrerent fuel tank, etc. The engines might work well, but the tractor then ends up looking chopped up. I don't think I'd bother with those conversions. Not only does the Honda work well with the 682/782, I think it fits in the tractor even better than the original Kohler KT did! The only thing I modified on the kit was fuel filter location to get it more out in the open rather than behind the engine for easier replacement. Other than that, everything is a breeze to service. They even included a high quality brass oil drain valve.
SEW was very helpful with me figuring out an electrical snafu I had when installing my new engine. The engine took about 5-6 hours to install. Good place, I really do recommend them.
