You can't get 180 degrees of crankshaft rotation between each of the 4 cylinders in the firing cycle. Seems to me the engine would run ruff.
Yes the firing will not be smooth. Like Tom said a John Deere, Also Harleys.
I did have a Couple John Deere when I was farming years ago.I also put a Harley 45 engine in my Cushman When I was 16 years old. We will see
