If the engine is a Honda GX clone, you might be able to sub in a Honda GX clone recoil assy.. Many of the engines used in Chinese import gens are typically a copy (or clone)of a Honda. Lots of GX clone parts out there at reasonable prices but would take some figuring out which size of engine you have.
I did find another website where a poster was looking for parts, some of the posts mentioned the same phone numbers for Cali and Texas given in this thread.
