They are made by in China,they are knock offs ,of the Honda engine
Troy-Bilt is a brand name of MTD. MTD currently makes all of their own engines in China.

Tecumseh made most, Briggs and Straton engines were used, but not many.
6.5 hp
The Briggs & Stratton engine company founded in 1908 owns and makes Simplicity snow blowers. These blowers include the four-cycle single-stage snow blower, the dual-stage snow blower, the large-frame dual-stage snow blower, and the Simplicity Signature Pro Commercial Duty dual-stage snow blower.
My guess is that the small battery used for such engines would not hold a charge very long in the constant cold weather a snow blower endures.
A guess-timate rule of thumb is 25cc per horsepower. So your snow blower would be about 7 horsepower.
The engines on the Troy-Bilt snow blowers are made by Zahng-Chen(I am not sure about that spelling). This according to the MTD dealer help line. My opinion is that they are good engines and only time will prove me right or wrong. I personally have sold hundreds of these over the past three years and the only ones that I know of that had major problems had been run into the ground, you do not use a 24" Troy-Bilt for commercial snow removal and expect it to last very long.
They are good at being efficient. Honda snow blowers all use Honda engines, which focus on fuel economy.
The best Ariens snow blowers are the older models with the Tecumseh engine. Tecumseh was the largest manufacture of small engines in North America but were bought out and sold on Dec.15, 2008. Another company bought the rights to it and still makes parts for the engines. Now Ariens uses China engines. I still use my 1976 Ariens Snow blower with the Tecumseh on it. Its built to last and last. All metal construction and starts on the first pull. So your best bet is to find a older Ariens (pre- 2008).
.030 (0.76 mm) gap. Use a Tecumseh resistor plug.
