Hi gr8t_28,
Welcome to the wonderful world of old Chevys! This is definitely the place to ask your questions and get knowledgeable answers.
Get to know these websites:
https://www.fillingstation.com/ http://earlychevyparts.com/ http://www.marxparts.com/ You can get pretty much all parts for the 1928 motor, just not carbs, heads, engine blocks etc. But gaskets and tune-up parts etc. are all available. One of your first purchases should be an owner's manual and a shop manual.
If you post more info about your '28, we can give you more focused advice. For example, what is printed on the Car ID plate, if it still exists? What are the casting numbers on the side of the engine? Also, do you have any pics that we can see?
Here is a thread that I think you'll want to read:

Here's my procedure for starting my '28 truck:
1. Turn on the gas valve at the bottom of the vacuum tank. If the truck has been sitting for a very long time, I occasionally have to prime the vacuum tank. I installed a 1/8 NPT plug at the top of the inlet line for this purpose.
2. Make sure the transmission is in neutral and you are not pushing down on the clutch pedal.
3. Fully retard the spark lever.
4. Pull the throttle lever down (open) a bit. Something like 3/4" to 1" down.
5. Turn on the key.
6. Pull and hold the choke out.
7. Step on the starter button.
After the engine starts and runs for a few seconds, I ease off the choke and slowly advance the spark until the spark lever is in its top position. Then, usually, the engine is running faster than I'd like so I back off the throttle lever, but still leaving the engine running at a fast idle.
After a few moments, when the engine sounds like it is running smoothly, I'll push the throttle lever all the way up so that the engine is idling correctly (500-600 rpm).
Cheers, Dean
