The reverse pulley is attached to an extended cam shaft. as far as I know there aren't any small engine Manufacturers that still make an engine like that. Mine is an econo horse as well I gave $1300.00 for it new 32 years ago. Needs new rims Mine are sooooo rusted that I'm afraid to change the tires in fear that the rim will fall apart.

I know a lot about a lot of things BUT I still have a lot to learn.
Life is what you make of it. So, why not make a working machine to make it easier.
