Cheap 16 HP Honda Clone Engine

I've been looking at the 420cc Honda clone engines at Harbor Freight. They have them on sale for $350 with a coupon. Plus sales tax, of course. These are some pretty good engines, according to what I have read. In fact some of the racing kart and garden tractor pulling guys remove the governor, work on the intake and exhaust a bit, and get over thirty horsepower at 7,000 RPM! So when I saw them for only three hundred bucks with free shipping, I just had to share. The video is from one of the reviewers of the engine on Amazon, who says he is rough on the engine and it still takes it. Only 20 left at this price as I write this, so if you want one you had better hurry!
