Re: Hf 99cc vs 66cc china 2 stroke reliability?
The HF 4-strokes, Huashengs, and Hondas are all modern industrial/commercial rated engines with cast iron cylinder sleeves, they'll run all day.
Most of them even have their own cooling fan. A lot of them are inexpensive.
The chinagirl dates back to the 1930's worker's movement. It's cheap and compact, designed for loaded commuting at low speeds.
They're fun, but compared to modern engines they are practically a toy.
