I would imagine it is a GXV motor, it would be stamped on the side of the block somewhere. There appears to be a carb manual for it uploaded.
I scored a free HR194 honda and foudn the reason it was replaced was somoe had turned off the hidden little fuel tap ontop of the carby.
To start things off I would pull the carb off, take the bowl off the bottom and make sure the little jet that goes up the center is clean. Also ensure that the choke butterfly closes when in the choke position.
