Thanks for the reply Philc. I was told the machine was running rough so the pump was pulled to clean with the injectors supposedly rebuilt at the same time.The previous owner said he reinstalled it but didn't get it timed properly and it either ran rough or not at all - can't remember exactly what he said. He also told me the pony motor "threw a rod" - whatever that meant - but like you, I don't see where it was taken apart. Maybe spun a rod? Hmmmm.
I'd like to start by putting the pump back together or buy a good used one. Whatever is the best option. Do you know anyone with parts I may need? Thank you.

Thanks gemdozer, I'll most likely need various parts I'm not aware of yet. Some pony parts and the magneto for sure. Not sure how we can contact each other than through this website?
gemdozer: I updated my contact info to show an email address.

get a copy of the parts book, service reference and owners book for your model and serial range. these are a big help. if your not a paid member of acmoc join us you get access to the magazine and tech library which is a huge trove of info thanks to the dedicated volunteers that keep it organised and the members submitting file scans to added to the expanding collection.
the dealers still have a number of parts for these older machines particularly gaskets, seals and bearings. the dealers may also be able to order pistons for you. but they need part numbers as they might not have the part book data anymore but they can search the parts database by part number.
as for a piston jp pistons in south australia can custom make pistons for many machines have a look on thier website they have a product list. it also might not hurt to give them a call. there maybe another engine that uses the same size and style of piston. ive done that with piston rings no direct match but something else used the same size rings.
if the injector pump and injectors are there any good injection shop should be able to service that for you. many of the larger dealers have thier own pump room and injection techs and can do this work.
magnetos can be rebuilt generally its a set of points and a condensor maybe replace the bearings.
the pilot engine exhuast manifold could be unobtainium i know the u series d4 ones are not available new.
there fairly simple a exhuast shop should be able to make you one.
dont forget to check the bit of exhuast tube that goes through the intake manifold as they often rust out this will prevent the main from starting and can lead to a dusted engine. hence it important to have working rain flaps on the exhuasts or cover them with a tin. another collector showed me a trick use spin-on oil filter bodies. he got a old spin-on filter off his truck and cut the thread end off and it works a treat as it's rounded on the end it doesnt hold water unlike a jam tin.
