I'm sure Textron didn't spend the $$$ to acquire Weber Motors with out need, and good reason. There is no more Weber Motors, as it is Textron Motors after the acquisition. Textron now has combined, and expanded all Textron Motors, and AC, engine development, engineering, design, and production. Without reasons? I doubt that. It is called in house control, quality, fit, and cost. They bought a engine manufacturer so they can easily justify R&D&E cost by doing so for their own complete product. Such as being one modular design. That's how to achieve the best vehicle weight, balance, and handling. The negative Weber market view? You can run down Weber Motors, but their reputation of very high quality products speaks for itself, as in being very well respected. You can't blame Weber for Poo's poor, not thought thru, misfitting, bad idea decisions. The components Poo used in those Weber applications is were the problems arose from. Poo admitted it was a poorly planned project from the very start. I'm betting that if, and when Poo brings a 4-stroke snowmobile to the market again, it will be with Poo's own engine/power. Time will tell us on both.
