I'm looking for a good used govenor for an Alco S1. I would also be interested in locating someone that can offer parts or service for one of these.

Unit has a PG installed, but I have an SI on the shelf that also needs work. Both are mechanical linkage throttles.

For parts and service I recommend Peaker Services, they have been very helpful in the past.
