Since I had the engine installed, I had to give it a try running it. At this point I had the electronic ignition installed and the carburetor rebuilt. I used an old gas tank from a snowblower and a used battery. I didn't have any cooling system, exhaust pipe or charging system, but I wasn't going to run it very long.
I turned on my switch to the ignition (old washing machine switch ["resources, not junk"]). Then I pushed down on the starter lever and it cranked! That was pretty exciting in itself. I kept cranking and soon it sputtered and came to life! Wow!
I ran it for a couple minutes maybe. It was enough to rev it up and down a bit. It sure sounded good. That was a big morale booster!
