Hi Bruce,

First, they don't sell the 2.4 anymore. Their Web site is out-of-date(what else is new in this industry) and still shows the 2.4 up there(they're working on a revamped site with correct info, and prices). It weighed the same as the 2.6 so they dropped it and just have the TS-42 (42cc, 2.6 cu in) now. It costs $529 shipped(no muffler) and is worth every penny of it. They have a pitts-style muffler available and also a 3 downtube exhaust diverter. I don't have the prices on these. The best way to get info from them is call. They will return e-mails promptly too. The parent company Southgate Aero has been in business for many years producing high-end engines for a variety of applications. They know how to build quality motors.

These motors are gorgeous. They are basically custom built for each customer, and take about 3 weeks to get one...though I might know where to find one in stock if you need it quickly.

I've had several brands of small gas engines over the years(BME, FPE, Quadra, Zenoah), and some big ones too, and these are the best built and highest quality I have seen. I have the 2.6 and it is exceptionally smooth because of the lower-end design and has superior power compared to the other 2.x engines out there. Their weight is on par with the other lightweight offerings. They weigh 4lbs 1oz complete with muffler, ignition and mount. The FPE and ZDZ are a few ounces lighter, but not enough to be significant and don't match up in other areas.
