Many people prefer the sound of 4-strokes, and the ones I've seen are very reliable. Many would argue that they sound just fabulous. I prefer a 4-stroke glow engine over a big gasser, simply because the 4-stroke is quieter. I do believe that multi-cylinder engines are far superior to their single or twin-cylinder counterparts. I witnessed an OS Pegasus pulling a Christen Eagle, and it was just amazing how low that machine would idle. It was fantastically smooth at all settings, then engine did not miss a beat. It just amazes me that more people have not discovered what a radial, in line, or 4-cylinder 4-cycle has to offer.

As for budget. I do believe the new OS AX 2-strokes will give the best in reliability, simplicity, and output for the money. They are also very quiet and pleasant to listen to. I have had some very positive experiences so far with my 46 AX. Not only will it literally pull stumps, I have heard more than my share of electrics that are considerably louder. I am sure many other AX owners would agree. I have enjoyed mine so much, in fact, that I just recently purchased a 55 AX to add to my collection.

Will I get a 4-stroke? Maybe. But my preference will be for one with at least 3 cylinders.
