It sounds like he is using eather a 2-stroke or a 4-stroke engine, being a steam engine don't use sparkplugs, distributor or a carberator. A 2-stroke engine would'nt work at all. The pressure on both sides of the piston trying to do the work would be equalized, and the pistons not doing the work would have high pressure on the bottom of the piston's only. The engine would'nt turn.
On a 4-stroke engine, you would have to make a camshaft from scratch. With the original cam, you would have a compression stroke. The pressure between the piston trying to do the work and the pressure in the cylinder on the compression stroke would equalize. The engine would'nt turn.
Tomorrow's lesson. Tank capacity + pressure vs. engine capacity + pressure required to do work.
