HT or "Happy Time", Is simply a "fit all" term to describe all the chinese 2 stroke bicycle engines. Thatsdax or BGF, It's still a HT engine. I believe it's derived from one of the first sellers of these engines from China, a company that called itself Happy Time. The engine itself is an old Russian design that the Chinese copied and mass marketed to the U.S.
And yeah, check yer exhaust. You can do this by simple removing the baffle, (cap,) from the end of your pipe. (and riding it.)
