If you research these "cheaper" engines, you will find those who love them and horror stories from those who got "duds". With these engines, "you put's down your money and takes your chances", now you are forwarned. Really, I haven't seen too many engines that couldn't be made to run. It may just be a tuning problem, but a lot of these are carburation problems. It seems that a lot of these manufacturers do not have the same quality standards that OS, and other "name brands" do, you can get away with this on engines to a point, but not carbs. I have purchased some of these engines in the past also, and had some good ones and some "duds". Most can be cured with a good carburetor, such as an OS or Perry. For my money these days, I'd rather spend 20-30 percent extra and know what I'm getting. Good luck with whatever decision you make. Flame suit on.
