they're different.
the 92-96 H22A is the A1 series. the 97+ is H22A4. the A4 has an open deck block and a bit more horsepower, like 5 hp.
other than that, they're about the same... but with the closed deck of the A1, it has some overheating issues, forcing the use of the open deck design on later models.
