try using zip ties or you can use copper wire and twist it tight with some pliers to secure the hosing

As you may or may not have noticed, you don't need to kickstart to start the engine if it has 4 pistons because it has no "dead space"; which essentially means there is always a piston in the power stroke (pushing down). this also means it can only spin one direction.<br>Love the video btw.

You need to 3d print thoes hose connections with a barb and use a zip tie or hose clamp. Also for the multi cylinder engines id make the hose diameter going into the splitter bigger then the size of the two coming out. Better air flow.

Also, engine piston firing order should be 1-3-2-4, if possible with lego pieces

Make sure you get a sheet of polycarbonate to keep between you and those flywheels because those can store a terrifying amount of energy. When those give out, you're actually at risk of being injured. Rotating objects are scary.
