Worth rebuilding?

I got one JUST like it right now in the same shape I am working loose. It will be to your benefit to remove the base plate and take it and have it bead blasted. I am going to do that with mine and even remove the throttle plates and shaft and lightly go over the shaft with emery cloth and mineral spirits and do the same with the shaft bores. Crossing my fingers the base plate will not need bushings. But if it does, no biggie.
