Will it run? 90 year old Farm engine with missing parts. Will it run on the cheap?

In this video I will take three busted McCormick-Deering M engines and make 1 runner. The issue is all of them are missing a Magneto and a fuel pump. Unfortunately the mag and fuel pump are out of my budget. But I manage to find away around both to get this engine running. I end up using a demand propane regulator for the fuel source. I ended up getting this on eBay for. 30 bucks. The magneto issue was solved by me using the wico ek style rod with spring with a limit switch. I can now hook up a battery and coil to make it run. In the. process of getting the engine going we had to pull the piston and rod, lap the valves and clean the cylinder. I also unfortunately broke the governor weights trying to unseize them. Engine will still need a complete restoration. But guess what she runs.
