Trying to identify this Stamford generator’s Isuzu engine model. It’s a 10Kw with an Isuzu 3-Cyl installed in an early 80s Newell. I believe there were only a couple options: 3AA1, 3AB1, 3AD1. Looking to perform a service and need to buy the correct parts. Any assistant would be appreciated.

According to the AA and AB manual, the engine number should be “stamped on the right front part of the cylinder body”.

From the terrible picture, I’d say it just under the injection pump at the front.
