That number worked. It is a 09P702-0138-H1. On these engines the model and the type are etch into the crankcase using a series dots like Honda uses.
The carb has both an idle jet and main jet.
I have haven't dealt the ready choke on the 09P but should be the same setup as the DOV750 so including a snap from that service manual.
I hopefully can PM you several links to info on my Google drive that should help.
