China ver. of gx 31 recoil stater needed

Hi I have one of these engines and I bought a real honda gx31 recoil, and it mounts, but the inner workings are smaller than the china.
It is for sale or trade...

This is the engine...

I need the right one this is the hangurdingdong brand, any help in locating will be a big help.

I think I will be selling one of my bikebugs... let me know if you have an interest.

I also have a kidney that I will let go cheap!
