No, I am not a Chinese spy looking to build the next clone "XXX" engine.....

I just like engines, and modifying them, studying them, etc.

Could anyone supply the port timing specs, and possibly pictures of the ports for the DLE 20, 30, and 55cc engines? They run quite well, and I would like to study them but can't afford to buy an example of each right now.

Thanks for any help or info,
