Ok, so it's finally my turn to try this

After much reading, re-reading, and agonizing

...
Last weekend I started tearing down a core IP to try my hand at a rebuild. I am glad I decided to get a core and not rebuild the pump that is on the car now so I could take my time and not stress. However, The core has been sitting for a while and is full of rust.

:'(
- What is the best way to clean everything? Should I soak the parts in penetrating oil and use a old tooth brush or a rag to remove the rust? I am guessing using caustic parts cleaners, a wire brush, or other harsh methods are not a good idea for the pump internals.
- Even after I get everything clean i am still going to have pump internals that are going to be pitted. The pitting will causes the parts to wear much faster I would think so the life of this pump is going to be comparability short, yes?
- I've been scratching my head about coming up with a tool for two the three sided for the governor lever. Any Ideas on that? I saw a set of Irwin "rounded bolt extractors" at my local autozone last week. there is a 13mm and the shape looks like it could work but, the sockets only look to be able to loosen bolts.
- I need to order a throttle shaft bushing, the shop I ordered my seals from said there are a couple of different types and they'd need to the measurements from the old bushing, so now that I have it apart what do I measure?
- I need to replace the bushing used to connect the cold start lever to the cable. The reseal kit doesn't appear to have one, anyone know that part number?
- As long as I am this far into it, should I replace the IP shaft bushings as well, is that a bench top home job or are special tools required?
Thanks.... Wish me success!!
