I've ran 2 stoke engines for years, mainly OS, Super Tigre. I bought my first 4 stroke last year and it was a Saito .82. It was one of the best engines I've ever come across. I liked it so well that I bought a Saito 1.00 and put in my Edge 540. There is nothing to these engines, just 40 min. break in at half throttle and your ready to go. I have never had one die on me or not want to start. These are very good quality engines and well worth the price and looking forward to the new Saito 1.25 coming out in December to put on my Seagull Laser 200. You can't beat the sound of a 4 stroke over a 2 stroke engine. They cost a little more but IMO they are well worth the money.
