Perkins Tune-up Shop?

[Jay Darst]

Does anyone know of really good place to have the Perkins tuned up?

Mine has a tendancy to shake a bit once in a while, thinking the fuel
injection timing could be adjusted as well as the injectors replaced
maybe...

Any comments on the things that should be considered with regard to
the generator tune-up would be greatly appreciated.
