Why? There is nothing wrong with experimenting on cheap engines as long you keep in mind it will never be a winner.

I am all for DIY and basically anyone can modify engines as long you can measure timings and know what to do. Use other engines to measure timings, set them in a list and note the feeling of the engine. With plenty listed you can see which rimings does what what will be a base to try some more. And yes, going beyond of what you see will be a trial and error
